Mathematics, 2023 In this paper, we introduce the b-triangular property in fuzzy b-metric space. Furthermore, we give some new fixed point results in fuzzy b-metric space for non-continuous mappings.

On the Fredholm Property of Bisingular Pseudodifferential Operators [PDF]
Integral Equations and Operator Theory, 2016 For operators belonging either to a class of global bisingular pseudodifferential operators on $R^m \times R^n$ or to a class of bisingular pseudodifferential operators on a product $M \times N$ of two closed smooth manifolds, we show the equivalence of their ellipticity (defined by the invertibility of certain associated homogeneous principal symbols)

Unique Fixed-Point Results in Fuzzy Metric Spaces with an Application to Fredholm Integral Equations
Journal of Function Spaces, 2021 This paper aims at proving some unique fixed-point results for different contractive-type self-mappings in fuzzy metric spaces by using the “triangular property of the fuzzy metric”.

Elliptic operators and their symbols
Demonstratio Mathematica, 2019 We consider special elliptic operators in functional spaces on manifolds with a boundary which has some singular points. Such an operator can be represented by a sum of operators, and for a Fredholm property of an initial operator one needs a Fredholm ...

Fredholm properties of evolution semigroups
Illinois Journal of Mathematics, 2004 The authors consider questions related to the linear differential equation \[ u'(t)= A(t)u(t) \] on a Banach space \(X\) in which the operators \(A(t)\) might be unbounded. Let \(\{U(t,\tau)\}_{t\geq\tau}\), \(t,\tau\in\mathbb{R}\), denote a strongly continuous exponentially bounded evolution family on \(X\).

Numerical Solution of Mixed Volterra – Fredholm Integral Equation Using the Collocation Method
مجلة بغداد للعلوم, 2020 Volterra – Fredholm integral equations (VFIEs) have a massive interest from researchers recently. The current study suggests a collocation method for the mixed Volterra - Fredholm integral equations (MVFIEs)."A point interpolation collocation method is ...

Generalized Fredholm Properties for Invariant Pseudodifferential Operators [PDF]
Acta Applicandae Mathematicae, 2012 We define classes of pseudodifferential operators on $G$-bundles with compact base and give a generalized $L^2$ Fredholm theory for invariant operators in these classes in terms of von Neumann's $G$-dimension. We combine this formalism with a generalized Paley-Wiener theorem, valid for bundles with unimodular structure groups, to provide solvability ...

Algebraic independence properties of the Fredholm series [PDF]
Journal of the Australian Mathematical Society, 1978 AbstractWe consider algebraic independence properties of series such as We show that the functions fr(z) are algebraically independent over the rational functions Further, if αrs (r = 2, 3, 4, hellip; s = 1, 2, 3, hellip) are algebraic numbers with 0 < |αrs|, we obtain an explicit necessary and sufficient condition for the algebraic independence of

Eigenvalue problem for differential Cauchy-Riemann operator with nonlocal boundary conditions
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014 We consider the reduced spectral problem for the Cauchy-Riemann operator with nonlocal boundary conditions to Fredholm linear integral equation of the second kind with a continuous kernel. The corresponding Fredholm determinant is defined for all spectral
