Past Events

In this talk I shall discuss the results which were obtained by several people: M.Avdeeva, F.Cellarosi, Dong Li and myself. Moebius function is one of the most important functions in number theory also connected with Riemann hypothesis. Its simplest...

Cube complexes have come to play an increasingly central role within geometric group theory, as their connection to right-angled Artin groups provides a powerful combinatorial bridge between geometry and algebra. This talk will introduce...

The concept of equivalence has played a central role in mainstream linguistic theory over the last century, e.g., in the definition of linguistic "form" in Bloomfield's (1926, 1933) attempts to axiomatize linguistic theory, in debates on the nature...

The consensus problem plays a central role in the theory of distributed computing. I will prove that consensus is impossible to solve in some asynchronous shared memory systems and I will present some algorithms for solving it in others, together...

An association scheme is a coloring of a complete graph satisfying certain regularity conditions. It is a generaliztion of groups and has many applications in algebraic combinatorics. Every association scheme yields a special matrix algebra called...

Program: 2:00pm Robert Calderbank (Duke University) Remembering Shannon Abstract - The foundation of our Information Age is the transformation of speech, audio, images and video into digital content, and the man who started the digital revolution was...

A video of this event is available on mathtube.org Abstract: The Langlands program, initiated in the 1960s, is a set of conjectures predicting a unification of number theory and the representation theory of groups. More precisely, the Langlands...

Classifying solutions is one of central themes in nonlinear partial differential equations. This is the content of various Liouville type theorems and more recently De Giorgi type conjectures. I will report recent progress towards De Giorgi's...

One of the distinguishing features of many living systems is their ability to move, to self-propel, to be active. Through their motion, either voluntarily or involuntarily, living systems are able self-assemble: birds flock, fish school, bacteria...
