Computational Math Day will have speakers and posters on a range of topics focussing on computation. Session Titles: - GAS sampling of polygons and knot probability ratios - Decidability of the existence of rational points on algebraic curves -...

Permutations are fundamental mathematical objects that arise naturally in many areas of mathematics and science. Pattern avoidance is an important facet of the study of permutations. With this workshop we hope to bring together different researchers...

This conference will involve presentations on the modeling and analysis of wave phenomena. It is one of the main venues where significant advances in the analysis and computational modeling of wave phenomena and exciting new applications are...

Abstract: Let s(n) denote the sum of the proper divisors of n, so, e.g., s(4)=1+2=3. A natural number n is called *perfect* if s(n)=n and *amicable* if s(n) =/= n but s(s(n))=n. For example, 6 is a perfect number, and 220 is an amicable number...

Abstract: Graphs and co-graphs (their matroid duals) dominate the structure of Totally Unimodular Matrices, real matrices whose subdeterminants lie in {0, +1, -1}. Thus some results about graph colorings and flows have common generalizations...

Abstract: Given a binary matroid $M$ represented by a binary matrix $A$ we can consider the binary matroid represented by $A$ plus an extra binary row$\\Sigma$. We call this a signed matroid and say that $(M,\\Sigma)$ is arepresentation of the signed...
