Oriented matroids are a class of matroids with a geometric flavor. We will see several examples of these, and find out why you should care about oriented matroids (or at

We will study the quite well known threshold for perfect matchings in G_{n,p}, and (hopefully) hypergraphs. Due to the relatively lengthy nature of these proofs, I will try to confine

Ergodic theory, being the study of invariant measures of dynamical systems, and Ramsey theory, being the study of structures within partitions of sets, seem like they would have little relation

Model theory, the area in mathematical logic which focuses broadly on mathematical theories and structures, has long been show to have applications to other areas of mathematics. Some of these

Counting the number of antichains in the Boolean algebra is known as Dedekind's problem and the asymptotic of this number is known. In this talk I will discuss the number

Advances in computing technology and the increasing interdisciplinarity of research have all encouraged the development of landscape scale mechanistic models of coupled ecological geophysical systems There has been little consensus however on the strategies and goals for these models One challenge is that ecology and the geosciences have embraced different

This talk will be an introduction to the combinatorial tool I call Fomin Growth Diagrams. These diagrams are natural number arrays augmented with partitions. The specific partitions that appear are

Keith doesn't like my research, because he thinks it's too esoteric. The goal of this talk is to convince him that he's only mostly (and not entirely) correct. The primary

I know where I will be on Wednesday at 12:10 PM, but I don't know what I'll be talking about. We will be able to apply this "uncertainty" to provide

We'll see how Furstenberg applied ergodic techniques to problems in combinatorics.

The union-closed sets conjecture states that for any union closed family of sets with only finitely many member sets (and not only the empty set) there is an element appearing

The hook lengths of a partition are defined using the Ferrer’s diagram of a partition. Fix a positive integer t. If a partition has no hook lengths that are multiples

Celebrating contributions of Eric Allender and Mike Saks to computer science and mathematics on the occasion of their 60th birthdays

The determinant complexity of a polynomial P in F[X1, X2, ..., Xn] is the smallest k such that the there is a k*k matrix N, whose entries are linear forms

Please join collaborating scientists from UC Berkeley and Rutgers University for a day long modeling symposium related to the Zika virus Enjoy presentations from leading researchers across the country as they discuss their latest research

General purpose obfuscation seeks to transform a program in a way that renders it maximally unintelligible while retaining its original input output functionality Practical and secure general purpose obfuscation would have many applications for protection of software and the secrets or intellectual property embedded within it Such obfuscation would enable

There are a variety of natural and man made disasters involving material transport that impact society The spread of an oil spill or radioactive material in the ocean or atmosphere are examples In order to improve emergency response we must be able to make better predictions about where this material

Deep Learning has created a transformation in the field of computer vision. Real time object and scene recognition in a robust manner is enabled by modern convolutional neural nets. In

Imagine that you are using a computational device -- e.g. your laptop or even a server -- that is much weaker than a huge stream of data -- e.g. scan
