2010/12/10
We give the solution of certain parabolic evolution problems (time-depending perturbations of the heat equation for the harmonic oscillator ) as explicit integrals on a space of continuous functions, ...
A remark on the subleading order in the asymptotics of the nonequilibrium emptiness formation probability
Nonequilibrium steady state emptiness formation probability Toeplitz theory

2010/12/1
We study the asymptotic behavior of the emptiness formation probability for large spin
strings in a translation invariant quasifree nonequilibrium steady state of the isotropic
XY chain. Besides the...
A short remark on negative energy densities and quantum inequalities
negative energy densities quantum inequalities
font style='font-size:12px;'>
2010/4/7
In quantum field theory it is generally known that the energy density may be negative at a given point in spacetime. A number of papers have shown that there is a restriction on this energy density wh...
A remark on Hadamard's inequality

2010/9/14
In this paper we establish some inequalities by using a fairly elementary analysis. As corollary we obtain the well known Hadamard’s inequality.

2010/9/14
A graph G with no isolated vertex is total domination vertex critical if for any vertex v of G that is not adjacent to a vertex of degree one, the total domination number of G−v is less than the...
A REMARK ON STABILITY OF A CLASS OF POSITIVE LINEAR DELAY SYSTEMS IN BANACH LATTICES

font style='font-size:12px;'>
2008/11/26
In this paper, we give an extension of the classical Perron-Frobenius theorem to a
class of positive quasi-polynomial operators. Then the obtained results are applied to
show that delay-independent ...
A Remark on Boundedness of Calderon-Zygmund Operators in Non-Homogeneous Spaces

2007/12/11
Let $\mu$ be a Radon measure on $\rd$ which may be non-doubling. The only condition satisfied by $\mu$ is that $\mu(B(x,r))\le Cr^n$ for all $x\in\rd$, $r>0$ and some fixed $0er, ...

2007/8/7
In this paper, we give characterizations for Bloch and normal functions. These caracterizations generalize the results of [1].
A REMARK ON PERIODIC SOLUTIONS OF SINGULAR HAMILTONIAN SYSTEMS WITH SUBLINEAR TERMS

In order to find explicit numerical approximation of K¨ahler-Einstein metric of projective manifolds, Donaldson introduced in [3] various operators with good properties to approximate classical operat...
A Remark on the Asymptotic Properties of Positive Homogeneous Maps on Homogeneous Lattices
Lyapunov Exponents asymptotic stability
font style='font-size:12px;'>
2010/3/1
An abstract version of Lyapunov exponents is defined for positive homogeneous maps on Homogeneous Lattices and a sufficient condition is given for the asymptotic stability of the map.
A remark on the Chisini conjecture

font style='font-size:12px;'>
2010/10/29
The Chisini conjecture asserts that a generic ramified covering over the complex projective plane of degree at least 5 is uniquely determined by its branch curve. We prove this for degree at least 12 ...

2010/11/2
The Gaussian isokinetic and isoenergetic thermostats of Hoover and Evans are formally equivalent as remarked by Gallavotti, Rondoni and Cohen. But outside of equilibrium the fluctuations are uncontro...
