A Layer-Adapted Numerical Method for Singularly Perturbed Partial Functional-Differential Equations

Axioms
This article describes an effective computing method for singularly perturbed parabolic problems with small negative shifts in convection and reaction terms. To handle the small negative shifts, the Taylor series expansion is used.

Singularly perturbed integral equations

Journal of Mathematical Analysis and Applications, 2006
The following singularly perturbed integral equation \[ \varepsilon u_\varepsilon(x) + \int_a^b K(x,y)u_\varepsilon(y)\,dy =f(x), \quad x\in[a,b]\tag{1} \] is considered, which becomes a Fredholm equation of first kind for \(\varepsilon=0\). The kernels \(K_\pm(x,y):=K(x,y)\) for \(\pm(x-y)>0\) are both smooth on \([a,b]\times[a,b]\) and might have ...

Perturbation formula of eigenvalues in a singularly perturbed domain

Journal of the Mathematical Society of Japan, 1993
The author deals with partial degeneration of a domain (the Dumbbell shaped domain) and an asymptotic behavior of a certain class of eigenvalues of the Laplacian with Neumann boundary conditions. For small \(\zeta>0\), the domain \(\Omega(\zeta)\) is expressed as follows \(\Omega(\zeta)=D_ 1\cup D_ 2\cup Q(\zeta)\subset\mathbb{R}^ n\) where \(Q(\zeta)\)
