A Logarithmic Image Prior for Blind Deconvolution [PDF]

open access: yes, 2015
Blind Deconvolution consists in the estimation of a sharp image and a blur kernel from an observed blurry image. Because the blur model admits several solutions it is necessary to devise an image prior that favors the true blur kernel and sharp image ...

Optimal heat kernel bounds under logarithmic Sobolev inequalities [PDF]

open access: yes, 2002
We establish optimal uniform upper estimates on heat kernels whose generators satisfy a logarithmic Sobolev inequality (or entropy-energy inequality) with the optimal constant of the Euclidean space.

Tikhonov regularization for an integral equation of the first kind with logarithmic kernel [PDF]

open access: yes, 2000
In this paper, we discuss stability and Tikhonov regularization for the integral equation of the first kind with logarithmic kernel. Since the kernel is analytic in our case, the problem is severely ill-posed.

Tikhonov Regularization For An Integral Equation Of The First Kind With Logarithmic Kernel [PDF]

open access: yes, 1998
In this paper, we discuss stability and Tikhonov regularization for the integral equation of the first kind with logarithmic kernel. Since the kernel is analytic in our case, the problem is severely ill-posed.

An inequality for a quadratic functional

open access: yesVietnam Journal of Mechanics, 2009
An inequality is proved for a quadratic functional with the logarithmic kernel. The best constant of this inequality and the corresponding function for which the equality holds are found precisely.

Logarithmic Bergman Kernel and Conditional Expectation of Gaussian Holomorphic Fields [PDF]

open access: yesThe Journal of Geometric Analysis, 2021
We prove the asymptotic of the logarithmic Bergman kernel. And as an application, we calculate the conditional expectation of density of zeros of Gaussian random sections of powers of a positive line bundle that vanish along a fixed smooth subvariety.

On the equivalence of heat kernel estimates and logarithmic Sobolev inequalities for the Hodge Laplacian [PDF]

open access: yes, 2006
In this paper we consider the Hodge Laplacian on differential k-forms over smooth open manifolds MN, not necessarily compact. We find sufficient conditions under which the existence of a family of logarithmic Sobolev inequalities for the Hodge Laplacian ...

Weighted Bergman Kernels for Logarithmic Weights [PDF]

open access: yesPure and Applied Mathematics Quarterly, 2010
We describe the boundary singularity of weighted Bergman kernels on smoothly bounded strictly pseudoconvex domains for weights which behave, roughly speaking, likely formal power series in defining function with coefficients which are polynomials in the logarithm of defining function.

Polynomial Decay Rate for Kirchhoff Type in Viscoelasticity with Logarithmic Nonlinearity and Not Necessarily Decreasing Kernel [PDF]

open access: yes, 2019
This paper describes a polynomial decay rate of the solution of the Kirchhoff type in viscoelasticity with logarithmic nonlinearity, where an asymptotically-stable result of the global solution is obtained taking into account that the kernel is not ...

Logarithmic correction to black hole entropy in universal low-energy string theory models

open access: yesJournal of High Energy Physics, 2023
We calculate the logarithmic correction to the entropy of asymptotically flat and AdS black holes (rotating, non-rotating, charged, and uncharged) embedded in Einstein-Maxwell-dilaton (EMD) theories with U(1)-charged.
