Probing the polarization characteristics of SS433 on mas scales
Z. Paragi, R. C. Vermeulen, D. C. Homan +5
We present a status report of dedicated circular polarization (CP) global VLBI observations of SS433. The total intensity image of the source is presented. We do not detect linear…
A Short Proof of the Zeilberger-Bressoud -Dyson Theorem
Ira M. Gessel, Guoce Xin
We give a formal Laurent series proof of Andrews's -Dyson Conjecture, first proved by Zeilberger and Bressoud.
A combinatorial proof of Postnikov's identity and a generalized enumeration of labeled trees
Seunghyun Seo
In this paper, we give a simple combinatorial explanation of a formula of A. Postnikov relating bicolored rooted trees to bicolored binary trees. We also present generalized formul…
Area comparison results for isotropic surfaces
Edward Goldstein
Consider a 2-plane and let be a bounded region in with a piecewise-smooth boundary. Let be the infimum of areas of all piecewise-smooth isot…
A Residue Theorem for Malcev-Neumann Series
Guoce Xin
In this paper, we establish a residue theorem for Malcev-Neumann series that requires few constraints, and includes previously known combinatorial residue theorems as special cases…
Automorphism groups of some affine and finite type Artin groups
Ruth Charney, John Crisp
We observe that, for each positive integer n > 2, each of the Artin groups of finite type A_n, B_n=C_n, and affine type \tilde A_{n-1} and \tilde C_{n-1} is a central extension of…
