Singular perturbation for nonlinear boundary-value problems
International Journal of Mathematics and Mathematical Sciences, 1979 Asymptotic solutions of a class of nonlinear boundary-value problems are studied. The problem is a model arising in nuclear energy distribution. For large values of the parameter, the differential equations are of the singular-perturbation type and ...

Multiple perturbations of a singular eigenvalue problem
, 2015 We study the perturbation by a critical term and a $(p-1)$-superlinear subcritical nonlinearity of a quasilinear elliptic equation containing a singular potential. By means of variational arguments and a version of the concentration-compactness principle

Singular Perturbation Problem in Boundary/Fractional Combustion
, 2015 Motivated by a nonlocal free boundary problem, we study uniform properties of solutions to a singular perturbation problem for a boundary-reaction-diffusion equation, where the reaction term is of combustion type.

Asymptotics of integrodifferential models with integrable kernels II
International Journal of Mathematics and Mathematical Sciences, 2003 Nonlinear singularly perturbed Volterra integrodifferential equations with weakly singular kernels are investigated using singular perturbation methods, the Mellin transform technique, and the theory of fractional integration.

Singular perturbations in foliations
Inventiones Mathematicae, 1989 Let M be a smooth manifold. A constraint system of class \(C^ r\) on M is a pair \(\{\) \(\{\) \(\tilde Z_{\epsilon}\},{\mathcal F}\}\) of \(C^ r\) family of vector fields on M, \(\{\) \(\bar Z_{\epsilon}\}\), \(0\leq \epsilon

Algebraic Perturbation Theorems of Core Inverse A㊮ and Core-EP Inverse A㊯
Journal of Mathematics, 2023 In this paper, the algebraic perturbation theorems of the core inverse A㊮ and core-EP inverse A㊯ are discussed for a square singular matrix A with different indices, and the expressions of the algebraic perturbation for these two new generalized inverses

Approximate solution to a hybrid model with stochastic volatility: a singular-perturbation strategy [PDF]
, 2009 We study a hybrid model of Schobel-Zhu-Hull-White-type from a singular-perturbation-analysis perspective. The merit of the paper is twofold: On one hand, we find boundary conditions for the deterministic non-linear degenerate parabolic partial ...

On fractional powers of singular perturbations of the Laplacian
, 2017 We qualify a relevant range of fractional powers of the so-called Hamiltonian of point interaction in three dimensions, namely the singular perturbation of the negative Laplacian with a contact interaction supported at the origin.

Fractal and FractionalIn this paper, we focus on the multiplicity of positive solutions for a singular tempered fractional initial-boundary value problem with a p-Laplacian operator and a changing-sign perturbation term.
