General: Model theory is one of the four major branches of mathematical logic, and has applications to algebra (e.g.field theory, algebraic geometry, number theory, and group theory), analysis (non-standard analysis, complex manifolds and Banach spaces) and theoretical computer science (via finite model theory) as well as to set theory and set-theoretic topology. This course is the first in a sequence of three courses. The purpose of this course is to present the basic concepts and techniques of model theory with an emphasis on pure model theory. The main theorem of the course is Morley's theorem. It will be presented in a way that permits several powerful extensions.
Contents include: Similarity types, structures, Abstract Elemntary Classes. Downward Lowenheim-Skolem theorem. Construction of models from constants, applications of the compactness theorem, model completness, elementary decideability results, cardinal transfer theorems, Henkin's omitting types theorem, prime models. Elementary chains of models, some basic two-cardinal theorems, saturated models (characterization and existence), special models, the monster model, basic results on countable models including Ryll-Nardzewski's theorem. Indiscernible sequences, and connections with Ramsey theory, Ehrenfeucht-Mostowski models. Introduction to stability (including the equivalence of the order-property to instability), chain conditions in group theory corresponding to stability/superstablity/omega-stability, strongly minimal sets, various rank functions, primary models, and a proof of Morley's categoricity theorem. Basic facts about infinitary languages, computation of Hanf-Morley numbers.
Prerequisites: This is a graduate level course, while at the beginning the pace will be slow in order to accommodate everybody, the course speeds up in the second half. In the past many, in fact the majority of students where undergraduates, so I decided to keep the prerequisites to the minimum of "an undergraduate level" course in logic.
