The aim of the course is to train students in creative problem solving in various areas of mathematics, in a manner simulating, to some extent, mathematical research (rather than ordinary courses, where homework assignments are, usually closely ? and quite obviously  related to the topics reviewed in class).

The problems will focus on topics in classical and modern mathematics that, due mostly to their interdisciplinary nature, are not ? as a rule ? covered in the core classes offered by the department (such topics as the axiom of choice and its applications, the BanachTarski paradox, transcendental number theory etc.). Classes will be divided between lectures, given by the instructor, filling in background material required to address the problems in question, and between students’ presentation of their solutions to the work sheets distributed previously.

The process diffusion limited aggregation, or DLA, is a remarkable process stemming from physics. Although it is known for almost 40 years, it still is mysterious and difficult to mathematically understand. Classically it has been studied in the plane. For this project we will simulate the process in other geometries, Euclidean as well as nonEuclidean. The goal is to obtain largescale simulations, which may lead to further understanding and new ideas. Further, we will use the simulations repeatedly to measure experimentally different quantities associated with DLA, such as growth rate, fractal dimension, etc.

The purpose of this course is to give one a sense of the history surrounding some of the major accomplishments in elementary mathematics. The course starts with a discussion of enumeration systems and with notions from early Egyptian and Greek mathematics; it then progresses with selected topics from the middleages to the 21st century. Stories about the notions and the personalities of many individuals associated with them are discussed. The course has a problem solving orientation.

The field of real numbers $\mathbb{R}$ is defined as the completion of the field of rational numbers $\mathbb{Q}$ with respect to the norm $\·\$. However, there are other norms on $\mathbb{Q}$, each corresponding to a prime number $p$, and the completion of $\mathbb{Q}$ with respect to any such norm leads to the field of $p$adic numbers, denoted by $\mathbb{Q}_p$. This is a topological complete field, and thus it makes sense to develop an analysis on it.
Many features of the $p$adic analysis are very different from familiar ones in real analysis. For example, “the first year calculus dream” of many students comes true: A series converges if and only if its general term goes to $0$. The overall picture of the $p$adic analysis makes impression of a surprising and beautiful one, and easier than its real counterpart. Nowadays, the $p$adic analysis has endless applications in geometry and number theory.
In this course we will study the field of $p$adic numbers from different points of view, stressing similarities to and deviations from the real numbers. If time permits the culmination of the course will be Tate’s thesis (1950), that uses $p$adic analysis to prove the meromorphic continuation of the zetafunction of Riemann and its functional equation.
 Arithmetic of $\mathbb{Q}_p$: sums and products, square roots, finding roots of polynomials.

 Topology of $\mathbb{Q}_p$: elementary topological properties, Euclidean models of $\mathbb{Z}_p$.
 Analysis on $\mathbb{Q}_p$: convergence of sequences and series, radius of convergence, elementary functions $\ln_p$, $\exp_p$, the space of locally constant functions.
 Harmonic analysis on $\mathbb{Q}_p$: characters of $\mathbb{Q}_p$, Haar measure, integration of locally constant functions, Fourier transform.
 The ring of adeles as an object unifying $\mathbb{Q}_p$ for all $p$: topological properties, integration and Fourier transform, Poisson summation formula.
 Tate’s thesis.

In this course we will discuss Cantor minimal systems. These are dynamical systems that admit a precise “digital representation” in the sense that the state space can be viewed as an infinite sequence of digits.There has been considerable recent interest in such systems. In this course we will consider formal versions of the question “when are two systems actually the same” . We will introduce and study the notions of isomorphism and orbit equivalence for dynamical systems. The objective of this course is to introduce students to basic notions in dynamical systems through contemporary results. Introduction: Dynamical systems in topological dynamics and ergodic theory, ergodicity and minimality, isomorphism of dynamical systems, the Cantor set, toplogical equivalence relations, orbit equivalence. Invariant measures. Cantor mimimal systems, Bratteli diagrams and the BratteliVershik Model, topological equivalence relations, Orbit cocyles, strong orbit equivalence, invariants for orbit equivalence and topological orbit equivalence.

In a random process, by definition, it is not possible to deterministically predict the next step. However, we will see in this course how to predict rigorously the long term behavior of processes. We will study in this course processes, known as Markov processes, in which the next step depends only on the current position. We will see that these processes are deeply related to electrical networks, and to notions from information theory such as entropy. We will develop techniques of discrete analysis, which are counterparts of classical analysis in the discrete setting. These notions are at the cutting edge of current research methods in these fields

The course will discuss arithmetic, analysis and geometry over $p$adic fields. The primary aim is to provide the necessary background for Dwork’s rationality theorem of Weil Zeta functions and to further developments in the subject.
In the first part of the course we will cover some classical applications of $p$adic numbers to elementary number theory including the local to global principle for quadratic forms.
In the second part we will study analysis: $p$adic functions and $p$adic power series and present Dwork’s proof.
Topics:

Rigidity, residues and duality over commutative rings. We will study rigid residue complexes. We will prove their uniqueness and existence, the trace and localization functoriality, and the indrigid trace homomorphism.

Derived categories in geometry. This topic concerns geometry in the wide sense. We will prove existence of Kflat and Kinjective resolutions, and talk about derived direct and inverse image functors.

Rigidity, residues and duality over schemes. The goal is to present an accessible approach to global Grothendieck duality for proper maps of schemes. This approach is based on rigid residue complexes and the indrigid trace. We will indicate a generalization of this approach to DM stacks.

Derived categories in noncommutative ring theory. Subtopics: dualizing complexes, tilting complexes, the derived Picard group, derived Morita theory, survey of noncommutative and derived algebraic geometry.
Generally speaking, algebraic geometry deals with geometric objects defined by polynomial equations. We will cover topics 13 below, and maybe one other topic, depending on the level of the students.
