Wronskians, dualities and FZZT-Cardy branes

Nuclear Physics B, 2016
The resolvent operator plays a central role in matrix models. For instance, with utilizing the loop equation, all of the perturbative amplitudes including correlators, the free-energy and those of instanton corrections can be obtained from the spectral ...

H(⋅,⋅)-Cocoercive Operator and an Application for Solving Generalized Variational Inclusions

Abstract and Applied Analysis, 2011
The purpose of this paper is to introduce a new H(⋅,⋅)-cocoercive operator, which generalizes many existing monotone operators. The resolvent operator associated with H(⋅,⋅)-cocoercive operator is defined, and its Lipschitz continuity is presented.

Fermion determinants in matrix models of QCD at nonzero chemical potential [PDF]

, 1997
The presence of a chemical potential completely changes the analytical structure of the QCD partition function. In particular, the eigenvalues of the Dirac operator are distributed over a finite area in the complex plane, whereas the zeros of the ...

RESOLVENT ESTIMATES OF THE DIRAC OPERATOR

Analysis, 1995
We shall investigate the asymptotic behavior of the extended resolvent R(s) of the Dirac operator as |s| increases to infinity, where s is a real parameter. It will be shown that the norm of R(s), as a bounded operator between two weighted Hilbert spaces of square integrable functions on the 3-dimensional Euclidean space, stays bounded.

Schur functions and their realizations in the slice hyperholomorphic setting [PDF]

, 2011
we start the study of Schur analysis in the quaternionic setting using the theory of slice hyperholomorphic functions. The novelty of our approach is that slice hyperholomorphic functions allows to write realizations in terms of a suitable resolvent, the

On the extended resolvent of the Nonstationary Schrodingher operator for a Darboux transformed potential

, 2005
In the framework of the resolvent approach it is introduced a so called twisting operator that is able, at the same time, to superimpose \`a la Darboux $N$ solitons to a generic smooth decaying potential of the Nonstationary Schr\"odinger operator and to

Resolvent expansions of 3D magnetic Schrödinger operators and Pauli operators [PDF]

Journal of Mathematical Physics
We obtain asymptotic resolvent expansions at the threshold of the essential spectrum for magnetic Schrödinger and Pauli operators in dimension three. These operators are treated as perturbations of the Laplace operator in L2(R3) and L2(R3;C2), respectively.

$(C,B)$-resolvents of closed linear operators

Novi Sad Journal of Mathematics, 2022
Summary: In this note, we analyze \((C,B)\)-resolvents of closed linear operators in sequentially complete locally convex spaces. We provide a simple application in the qualitative analysis of solutions of abstract degenerate Volterra integro-differential equations.
