Spectral properties of a type of integro-differential stiff problems

We consider an integro-differential stiff problem, which can be used as a model for the vibrations of a body with hnear viscoelasticity at large times First, the problem is introduced in the framework of the theory of semigroups in Hubert spaces and then, an asymptotic expansion ofihe solution is obtained Fwally, it is shown the double convergence, when e —• 0 + , ofthe eigenvalues of the probl...

On a class of integro-differential problems

A hybrid method with optimal stability properties for the numerical solution of stiff differential systems

In this paper, we consider the construction of a new class of numerical methods based on the backward differentiation formulas (BDFs) that be equipped by including two off--step points. We represent these methods from general linear methods (GLMs) point of view which provides an easy process to improve their stability properties and implementation in a variable stepsize mode. These superioritie...

Fractional type of flatlet oblique multiwavelet for solving fractional differential and integro-differential equations

The construction of fractional type of flatlet biorthogonal multiwavelet system is investigated in this paper. We apply this system as basis functions to solve the fractional differential and integro-differential equations. Biorthogonality and high vanishing moments of this system are two major properties which lead to the good approximation for the solutions of the given problems. Some test pr...
