Numerical Solution of Nonlinear Backward Stochastic Volterra Integral Equations
This work uses the collocation approximation method to solve a specific type of backward stochastic Volterra integral equations (BSVIEs). Using Newton’s method, BSVIEs can be solved using block pulse functions and the corresponding stochastic operational

DIRAC OPERATOR IN MATRIX GEOMETRY [PDF]
We review the construction of the Dirac operator and its properties in Riemannian geometry, and show how the asymptotic expansion of the trace of the heat kernel determines the spectral invariants of the Dirac operator and its index. We also point out that the Einstein–Hilbert functional can be obtained as a linear combination of the first two ...

Euler Operational Matrix of Integration and Collocation Method for Solving Functional Integral Equations [PDF]
In this paper, the functional Volterra integral equations of the Hammerstein type are studied. First, some conditions that ensure the existence and uniqueness of the solutions to these equations within the space of square-integrable functions are ...

Matrix valued p-convolution operators [PDF]
Let \(G\) be a locally compact group with Haar measure, and let \(M_n\) be the set of \(n \times n\) matrices, with the \(C^{\ast}\)-norm, over the complex numbers. Throughout this review \(p\) will denote a real number strictly greater than one. We will write \(L^p(G, M_n)\) to indicate the space of \(p\)-integrable functions from \(G\) into \(M_n ...

An Operational Matrix of Fractional Derivatives of Laguerre Polynomials
In this paper, we derive the Laguerre operational matrix (LOM) of fractional derivatives, which is applied together with the spectral tau method for numerical solution of general linear multi-term fractional differential equations (FDEs) on the half line.

Distributed-order fractional differential operators provide a powerful tool for mathematical modeling of multiscale multiphysics processes, where the differential orders are distributed over a range of values rather than being just a fixed fraction.
