Thermodynamic Partition Function of Matrix Superstrings

open access: yes, 2001
We show that, in the limit of zero string coupling, $g_s \to 0$, the thermodynamic partition function of matrix string theory is identical to that of the finite temperature, discrete light-cone quantised (DLCQ) type IIA superstring.

A Formula for the Fréchet Derivative of a Generalized Matrix Function

open access: yesSIAM Journal on Matrix Analysis and Applications, 2017
We state and prove an analogue of the Daleckii--Krein theorem, thus obtaining an explicit formula for the Frechet derivative of generalized matrix functions.

Variational Properties of Matrix Functions via the Generalized Matrix-Fractional Function [PDF]

open access: yesSIAM Journal on Optimization, 2019
We show that many important convex matrix functions can be represented as the partial infimal projection of the generalized matrix fractional (GMF) and a relatively simple convex function. This representation provides conditions under which such functions are closed and proper as well as formulas for the ready computation of both their conjugates and ...

Some Representations of the Modified Degenerate Gamma Matrix Function [PDF]

open access: yesSahand Communications in Mathematical Analysis
The main goal of this article is to extend the concept of special matrix functions through the study of modified degenerate Gamma matrix function. For this, the modified degenerate Gamma matrix function has been introduced and some of its properties have

Four-point function in the IOP matrix model [PDF]

open access: yes, 2016
The IOP model is a quantum mechanical system of a large-$N$ matrix oscillator and a fundamental oscillator, coupled through a quartic interaction. It was introduced previously as a toy model of the gauge dual of an AdS black hole, and captures a key ...

Stochastic Conditioning of Matrix Functions [PDF]

open access: yesSIAM/ASA Journal on Uncertainty Quantification, 2014
We investigate the sensitivity of matrix functions to random noise in their input. We propose the notion of a stochastic condition number, which determines, to first order, the sensitivity of a matrix function to random noise. We derive an upper bound on the stochastic condition number that can be estimated efficiently by using “small-sample ...

Recovery of the Dirac system from the rectangular Weyl matrix function [PDF]

open access: yes, 2011
Weyl theory for Dirac systems with rectangular matrix potentials is non-classical. The corresponding Weyl functions are rectangular matrix functions. Furthermore, they are non-expansive in the upper semi-plane.

A remark on the three approaches to 2D Quantum gravity

open access: yes, 2010
The one-matrix model is considered. The generating function of the correlation numbers is defined in such a way that this function coincide with the generating function of the Liouville gravity.
