In this talk we give combinatorial proofs of q-Stirling identities using restricted growth words. This includes a poset theoretic proof of Carlitz’s identity, a new proof of the q-Frobenius identity of Garsia and Remmel and of Ehrenborg’s Hankel q-Stirling determinantal identity. We also develop a two parameter generalization to unify identities of Mercier and include a symmetric function versi...

Secure communication is the act of conveying information from a sender to a receiver, while simultaneously hiding it from everyone else. Secure communication is the oldest application of cryptography, and remains the centerpiece of cryptography to this day. After all, the word cryptography means “hidden writing” in Greek. So, secure communication is a natural place to start our study of cryptog...

We consider the Standard Model on a non-commutative space and expand the action in the non-commutativity parameter θ . No new particles are introduced, the structure group is SU(3)×SU(2)×U(1). We derive the leading order action. At zeroth order the action coincides with the ordinary Standard Model. At leading order in θ we find new vertices which are absent in the Standard Model on commutative ...
متن کامل$n$-cocoherent rings, $n$-cosemihereditary rings and $n$-V-rings
Let $R$ be a ring, and let $n, d$ be non-negative integers. A right $R$-module $M$ is called $(n, d)$-projective if $Ext^{d+1}_R(M, A)=0$ for every $n$-copresented right $R$-module $A$. $R$ is called right $n$-cocoherent if every $n$-copresented right $R$-module is $(n+1)$-coprese-nted, it is called a right co-$(n,d)$-ring if every right $R$-module is $(n, d)$-projective. $R$...

The purpose of this talk is to review a few issues concerning noncommutativity arising from String Theory. In particular, it is shown how in Type IIB Theory, the annihilation of a D3 − D3 brane pair yields a D1−string. This object, in the presence of a large B−field and fermions, happens to be a complex noncommutative soliton endowed with superconductivity. INTRODUCTION Type IIB Superstring The...
