Existence of traveling waves in a delayed convecting shallow water fluid model

open access: yesElectronic Research Archive, 2023
This paper investigates a delayed shallow water fluid model that has not been studied in previous literature. Applying geometric singular perturbation theory, we prove the existence of traveling wave solutions for the model with a nonlocal weak delay ...

Generalized lower characteristic involving measures of non-strict singularity

open access: yesTopological Algebra and its Applications, 2023
This work establishes a connection between the class of generalized lower characteristic operators and [⋅]a{\left[\cdot ]}_{a} acting on a Banach space involving measures of non-strict singularity.

Fredholm representation of multiparameter Gaussian processes with applications to equivalence in law and series expansions [PDF]

open access: yes, 2015
We show that every multiparameter Gaussian process with integrable variance function admits a Wiener integral representation of Fredholm type with respect to the Brownian sheet.

Nonlinear PDEs for gap probabilities in random matrices and KP theory [PDF]

open access: yes, 2012
Airy and Pearcey-like kernels and generalizations arising in random matrix theory are expressed as double integrals of ratios of exponentials, possibly multiplied with a rational function. In this work it is shown that such kernels are intimately related

Fredholm-Lagrangian-Grassmannian and the Maslov index [PDF]

open access: yes, 2003
We explain the topology of the space, so called, Fredholm-Lagrangian-Grassmannain and the quantity ``Maslov index'' for paths in this space based on the standard theory of Functional Analysis.

A Generalized Nonlinear Volterra-Fredholm Type Integral Inequality and Its Application

open access: yesJournal of Applied Mathematics, 2014
We establish a new nonlinear retarded Volterra-Fredholm type integral inequality. The upper bounds of the embedded unknown functions are estimated explicitly by using the theory of inequality and analytic techniques.

Bifurcation Results for a Class of Perturbed Fredholm Maps

open access: yesFixed Point Theory and Applications, 2008
We prove a global bifurcation result for an equation of the type Lx+λ(h(x)+k(x))=0, where L:E  →  F is a linear Fredholm operator of index zero between Banach spaces, and, given an open subset Ω of E, h,k:Ω×[0,+∞)

Functional equations and separation of variables for exact g-function

open access: yesJournal of High Energy Physics, 2020
The g-function is a measure of degrees of freedom associated to a boundary of two-dimensional quantum field theories. In integrable theories, it can be computed exactly in a form of the Fredholm determinant, but it is often hard to evaluate numerically ...

Some Nonlinear Delay Volterra–Fredholm Type Dynamic Integral Inequalities on Time Scales

open access: yesDiscrete Dynamics in Nature and Society, 2018
We are devoted to studying a class of nonlinear delay Volterra–Fredholm type dynamic integral inequalities on time scales, which can provide explicit bounds on unknown functions.
