Lipschitz stability for generalized ordinary differential equations and impulsive retarded differential equations [PDF]
Electronic Journal of Qualitative Theory of Differential Equations, 2019 We consider a class of retarded functional differential equations with preassigned moments of impulsive effect and we study the Lipschitz stability of solutions of these equations using the theory of generalized ordinary differential equations and ...

Two generalized Tricomi equations [PDF]
, 2021 In this note we give existence results for the generalized Tricomi equations Ru′ ′+ Bu= f and (Ru′)′+Bu=f with suitable boundary data where R may be an operator (or a function) depending also on time assuming positive, null and negative sign, while B is ...

Recurrence coefficients for discrete orthonormal polynomials and the Painlevé equations [PDF]
, 2013 We investigate semi-classical generalizations of the Charlier and Meixner polynomials, which are discrete orthogonal polynomials that satisfy three-term recurrence relations.

Generalized gravity from modified DFT
Journal of High Energy Physics, 2017 Recently, generalized equations of type IIB supergravity have been derived from the requirement of classical kappa-symmetry of type IIB superstring theory in the Green-Schwarz formulation.

Stability of generalized Newton difference equations
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012 In the paper we discuss a stability in the sense of the generalized Hyers-Ulam-Rassias for functional equations Δn(p, c)φ(x) = h(x), which is called generalized Newton difference equations, and give a sufficient condition of the generalized Hyers-Ulam ...

Generalized Stochastic Fokker-Planck Equations
Entropy, 2015 We consider a system of Brownian particles with long-range interactions. We go beyond the mean field approximation and take fluctuations into account.

Indefinite Hamiltonian systems whose Titchmarsh–Weyl coefficients have no finite generalized poles of non-positive type [PDF]
, 2013 The two-dimensional Hamiltonian system (*) y'(x)=zJH(x)y(x), x∈(a,b), where the Hamiltonian H takes non-negative 2x2-matrices as values, and $J:= \begin{pmatrix} 0 & -1 \\ 1 & 0 \end{pmatrix}$, has attracted a lot of interest over the past decades ...

A matrix method for system of integro-differential equations by using generalized Laguerre polynomials [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2016 The purpose of this research is to present a matrix method for solving system of linear Fredholm integro-differential equations(FIDEs) of the second kind on unbounded domain with degenerate kernels in terms of generalized Laguerre polynomials(GLPs).
