About LaTeX:
At some point in your math carreer you will, most probably, have
to write math assiginments or perhaps even a thesis. Now is
as good a time as ever to start learning it, so that you can
produce assignments in a professional format. You are of
course free to hand write assignments or use some other word
processor, but TeX produces so much more legible and neat
documents that you will regret in hindsight not having used it
earlier. Rather than learning the "bare bones" language TeX,
most people nowadays opt for the more user friendly LaTeX (the
most popular dialect presently is pdflatex which outputs a PDF
file). There are plenty free programs out there to write
(La)TeX, for almost all imaginable platforms. Here are some
links to start you off:

- Assignment #1 on definable
subsets.
- Assignment #2: study the following
proof of Tarski's theorem by Muchnik.
- Final: as agreed, you have until Dec
21 (your local time--so if you're running out of time, you can move
to Hawaii for a couple of extra hours) to submit, by email, your
solution (preferably in TeX but you can instead scan your notes as
well). I will confirm receipt, so if you don't get this from me,
then something went wrong with the submission (too large a file is
often the reason). You are supposed to work on these problems by
yourself and not discuss it with the others! Here is the final.
About LaTeX:
At some point in your graduate carreer you will, most probably, have
to learn TeX to write math papers or a dissertation. Now is as
good a time as ever to start learning it, so that you can produce
assignments in a professional format. You are of course free to
hand write assignments or use some other word processor, but TeX
produces so much more legible and neat documents that you will regret
in hindsight not having used it earlier. Rather than learning
the "bare bones" language TeX, most people nowadays opt for the more
user friendly LaTeX (the most popular dialect presently is pdflatex
which outputs a PDF file). There are plenty free programs out

About LaTeX:
At some point in your graduate carreer you will, most probably, have
to learn TeX to write math papers or a dissertation. Now is as
good a time as ever to start learning it, so that you can produce home
work solutions in a professional format. You are of course free
to hand write assignments or use some other word processor, but TeX
produces so much more legible and neat documents that you will regret
in hindsight not having used it earlier. Rather than learning
the "bare bones" language TeX, most people nowadays opt for the more
user friendly LaTeX (the most popular dialect presently is pdflatex
which outputs a PDF file). There are plenty free programs out
there to write (La)TeX, for almost all imaginable platforms.

- Model Theory II (MATH 80200, T/Th, 2pm-3:30pm);
Prof. Rothmaler is offering an advanced model-thory course
(see his syllabus), which is a
continuation of the current class and the model-theory seminars of the
last few semesters. He told me that he will start with a quick
introduction covering the remaining chapters of his book (Chapters
11-14.5), for anybody who has not been exposed to this material through
the seminars. I will assist those that are interested in this course
through an IS, see next item:
- Independent study (MATH 89904, meeting hours tba):
if you are interested in the above advanced model-theory course by Prof.
Rothmaler (see previous item), but have not passed the Logic Qualifier,
you can instead register for an IS with me, take the course, and we then
will get together to "fill in the gaps" and discuss the material. You
wouldn't be responsible for any course work, but will receive three
credits for working with me.
- Model-theory
seminar (GC 6417, Fridays 12:30-1:45PM; organized by P.
Rothmaler and H. Schoutens):
Various topics in model theory.
Some of the topics to be studied in this semester's seminar are
described below. They vary in degree of model-theoretic
sophistication and prerequisites. Topic 1 and largely also Topic 3
require no more than some general understanding of first-order
semantics (as provided in Logic I). Topic 2 will be rather
complementary to Model Theory II, also offered this semester (see
above). Other topics may be added when appropriate.
- 1. Interpretations. The method of interpreting
one kind of structure syntactically in another is a very old one. As
an example, think of the field of complex numbers as interpreted in
the field of real numbers or of the field of rational numbers in the
ring of integers (coincidentally in both cases by pairs of elements
of the ambient structure). Quite obviously, these interpretations
work on a syntactic level using first-order formulas. The goal is to
establish some well-known classical features of such interpretations
that play a fundamental role in all areas of mathematical logic. We
will start with the elementary [R, Sect. 6.4] and may go on to apply
this to Malcev's local theorems, the very first application of model
theory to classical mathematics, if enough interest in (purely)
group theoretic applications can be mustered [R, Sect. 6.5] (other
applications could be studied instead). Ref: [Mal], [M, Sect. 1.3],
[R].
- 2. Pairs of stable structures. By a pair of
L-structures, (N, M), we mean an L-structure N considered in an
expansion L(P) of L by a unary predicate P whose interpretation in N
constitutes a proper elementary substructure M of N (as
L-structure). There are many natural examples of such pairs, e.g.
any extension of algebraically closed fields K/k can be thought of
as such a pair (K, k). Interestingly, we will see that the latter,
though of infinite Morley rank (as opposed to rank 1 for single
algebraically closed fields), are still omega-stable. We will study
a much more general result due to Casanovas and Ziegler [CZ] showing
that under a reasonably general extra condition (satisfied by
strongly minimal theories such as algebraically closed fields) pairs
of stable structures are stable. Ref: [P1], [CZ].
- 3. Model theory of modules. One of the simplest
examples of strongly minimal structure are vector spaces over fields
(even division rings). So vector spaces are at the lowest level of
the stability hierarchy. Surprisingly, even if we replace the field
or division ring by the ring of integers (to obtain all abelian
groups) or just any, even non-commutative ring (to obtain arbitrary
modules), we do not leave the realm of stable theories. By one of
Shelah's fundamental theorems of stability theory, this means that
despite the vast richness of the class of abelian groups or even all
modules, no infinite linear order, not even in the most rudimentary
sense, can be first-order definable in a module. The standard
reference is [Pr], but we may start with [P2, Sect. 6.5] and [H,
Appendices 1 and 2] and continue with the unpublished [Rot] as
preparation before we go into other sources. Ref: [H], [P2], [Pr],
[Rot], [R, Ch.15].

Chromatic
products in algebra and geometry
Ultraproducts of rings, and variant
constructions, called chromatic
products, can be used to prove some deep theorems in (pure) algebra and
algebraic geometry. One such application, which I have already lectured
about in Leuven a few years back, is tight closure theory in
characteristic zero. In this lecture series, I will describe further
applications, obtained by similar principles.
Lecture I (Mon. June 21, 14:00) "Ultrarings and uniform bounds"
- (Ia) Definition of ultrarings: algebraic, sheaf-theoretic,
and geometric constructions;
(Ib) Lefschetz hulls as adjoints of the forgetful functor: flat
embeddings of rings inside ultrarings,

(Id) Application 2: uniform bounds in algebra for linear properties
(Ie) (optional) Application 3: tight closure in characteristic zero
(If) (optional) Application 4: big Cohen-Macaulay algebras in
characteristic zero
Lecture II (Wed. June 23, 14:00) "Protoproducts and homological
conjectures"

(IIb) Application 1: uniform bounds for the etale protograde
(IIc) (optional) Ax-Kochen-Ershov principle and transfer in mixed
characteristic
(IId) (optional) Application 2: Asymptotic homological conjectures
(example: the Monomial Conjecture)
Lecture III "Cataproducts and classification of singularities"
(IIIa) Cataproducts and catapowers:
definition and properties
(IIIb) Similarity relation on germs of singularities.
(IIIc) Application 1: Borel classifications and the jet metric.
(IIId) Application 2: ring properties via uniform arithmetic.
(IIIe) (optional) Application 3: Asymptotic homological conjectures
(example: the New Improved Intersection Conjecture)
Lecture IV "Ultra-Frobenius and
rational singularities"
(IVa) The action of the ultra-Frobenius on
ultra-cohomology
