Equidistribution of zeros of random holomorphic sections
We study asymptotic distribution of zeros of random holomorphic sections of
high powers of positive line bundles defined over projective homogenous
manifolds. We work with a wide class of distributions that includes real and
complex Gaussians. As a special case, we obtain asymptotic zero distribution of
multivariate complex polynomials given by linear combinations of orthogonal
polynomials with i.i.d. random coefficients. Namely, we prove that normalized
zero measures of m i.i.d random polynomials, orthonormalized on a regular
compact set are almost surely asymptotic to the
equilibrium measure of .Comment: Final version incorporates referee comments. To appear in Indiana

Asymptotic normality of linear statistics of zeros of random polynomials
In this note, we prove a central limit theorem for smooth linear statistics
of zeros of random polynomials which are linear combinations of orthogonal
polynomials with iid standard complex Gaussian coefficients. Along the way, we
obtain Bergman kernel asymptotics for weighted -space of polynomials
endowed with varying measures of the form under
suitable assumptions on the weight functions .Comment: Minor revisions, references added. To appear in Proc. of Amer. Math.

Thermodynamics of regular black holes with cosmic strings
In this article, the thermodynamics of regular black holes with a cosmic
string passing through it is studied. We will observe that the string has no
effect on the temperature as well as the relation between entropy S and horizon
area A.Comment: Accepted for publication in EPJ Plus, 6 page
Regularity of the Optimal Stopping Problem for Jump Diffusions
The value function of an optimal stopping problem for jump diffusions is
known to be a generalized solution of a variational inequality. Assuming that
the diffusion component of the process is nondegenerate and a mild assumption
on the singularity of the L\'{e}vy measure, this paper shows that the value
function of this optimal stopping problem on an unbounded domain with
finite/infinite variation jumps is in with . As a consequence, the smooth-fit property holds.Comment: To Appear in the SIAM Journal on Control and Optimizatio
