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...
The location of the hot spot in a grounded convex conductor
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...
On the limit behavior of metrics in continuity method to Kahler-Einstein problem in toric Fano case
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...
Aligned Interference Neutralization and the Degrees of Freedom of the 2x2x2 Interference Channel
Aligned Interference Neutralization Degrees of Freedom 2x2x2 Interference Channel
2011/1/20
We show that the 2 2 2 interference network, i.e., the multihop interference network formed by concatenation of two 2-user interference channels achieves the min-cut outer bound value of 2 DoF, fo...
We use the moduli matrix approach to study the moduli space of 1/4 BPS kinks supported by vortices in the Higgs phase of N = 2 supersymmetric U(N) gauge theories when non-zero masses for the matter hy...
A new characterization of Carmichael numbers via a generalization of Lehmer's totient problem
new characterization Carmichael numbers generalization of Lehmer's totient problem
2011/1/20
Lehmer’s totient problem consists of determining the set of positive integers n such that '(n)|n − 1 where ' is Euler’s totient function. Any such composite number is a Carmichael number.
Recently Simmons and Cardy predicted a formula for the prob-ability that the chordal SLE8/3 path passes to the left of two points in the upper half-plane. The purpose of this note is to bring it to at...
An analysis of the field theoretic approach to the quasi-continuum method
analysis of the field theoretic quasi-continuum method
2011/1/20
Using the orbital-free density functional theory as a model theory, we present an analysis of the field theoretic approach to quasi-continuum method. In particular,by perturbation method and multiple ...
The quasi-periodic doubling cascade in the transition to weak turbulence
Transition to turbulence torus bifurcation
2011/3/3
The quasi-periodic doubling cascade is shown to occur in the transition from regular to weakly turbulent behaviour in simulations of incompressible Navier-Stokes flow on a three-periodic domain.
A new problem formulation is presented for the Gaussian interference channels (GIFC) with two
pairs of users, which are distinguished as primary users and secondary users, respectively. The primary u...
It is easy to see that no n-REA set can form a (non-trivial) min-imal pair with 00 and only slightly more dicult to observe that no !-REA set can form a (non-trivial) minimal pair with 000.
This short text is for readers who are confident in basic category theory but know little or nothing about toposes. It is based on some impromptu talks given to a small group of category theorists. I ...
Note on harmonic sums and alternating Euler sums
Harmonic sums Alternating Euler sums Multiple zeta values
2011/2/25
The explicit formulas expressing harmonic sums via alternating Euler sums (colored multiple zeta values) are given, and some explicit evaluations are given as applications.
Together with the concept of reversibility, another relevant physical notion is time-symmetry, which expresses that there is no way of distinguishing between backward and forward time directions. This...
