In [L-Y5] (D(6): arXiv:1003.1178 [math.SG]) we introduced the notion of Azumaya C1-manifolds with a fundamental module and morphisms therefrom to a complex manifold. In the current sequel, we use this...

Combinatorial Multi-Armed Bandit Problem Markovian Rewards
2011/1/21
We consider a combinatorial generalization of the classical multi-armed bandit problem that is defined as follows.There is a given bipartite graph of M users and N M resources.
Linear space of spinor monomials and realization of the Nambu-Goldstone fermion in the Volkov-Akulov and Komargodski-Seiberg Lagrangians
Linear space of spinor monomials realization Nambu-Goldstone fermion Volkov-Akulov Komargodski-Seiberg Lagrangians
2011/3/2
The analytical algorithm previously proposed by the author for matching the Volkov-Akulov (VA) and Komargodski-Seiberg (KS) actions describing the Nambu-Goldstone (NG) fermion, is discussed.
Proving the existence of an operator that connects non-perturbed states to perturbed states, an alternative derivation of the Dalgarno-Lewis method is given.To illustrate that the Dalgarno-Lewis metho...

Orthogonal polynomials for a family of weight functions on [1; 1]2,W ; ; (x; y) = jx + yj2 +1jx yj2 +1(1 x2) (1 y2) ; are studied and shown to be related to ...
Relative Equilibria of the $(1+N)$-Vortex Problem
Relative Equilibria $(1+N)$-Vortex Problem
2011/1/18
We examine existence and stability of relative equilibria of the n-vortex problem specialized to the case where N vortices have small and equal circulation and one vortex has large circulation.

Let M be a closed orientable Riemannian surface. Consider an SO(3)-connection A and a Higgs field : M → so(3). The pair (A,) naturally induces a cocycle over the geodesic flow of M. We classify (up...
Let {En} be the Euler numbers. In the paper we determine E2mk+b − Eb modulo 2m+7, where k,m are positive integers with m 4 and b 2 {0, 2, 4, . . . }.
We study f(R)-gravity with torsion in presence of the most general ELKO matter. We check the consistency of the conservation laws with the matter field equations; we discuss some mathematical features...

Heat equation hot spot eigenfunctions Santalo point
2011/2/24
We investigate the location of the (unique) hot spot in a convex heat conductor with unitary initial temperature and with boundary grounded at zero temperature.
Ordinary varieties and the comparison between multiplier ideals and test ideals II
Test ideals multiplier ideals ordinary variety
2011/1/21
We consider the following conjecture: if X is a smooth n-dimensional projective variety over a field k of characteristic zero, then there is a dense set of reductions Xs to positive characteristic suc...

limit behavior of metrics continuity method Kahler-Einstein problem
2011/2/25
This is a continuation of paper [7]. On any toric Fano manifold, we discuss the behavior of limit metric of a sequence of metrics, which are solutions to a continuity family of complex Monge-Amp`ere e...
