Exact and Approximate Solutions for Some Classes of the Inhomogeneous Pantograph Equation

open access: yesAxioms, 2023
The standard pantograph delay equation (SPDDE) is one of the famous delay models. This standard model is basically homogeneous in nature and it has been extensively studied in the literature. However, the studies on the general inhomogeneous form of such

Solving higher order Fuchs type differential systems avoiding the increase of the problem dimension

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
In this paper, we develop a Frobenius matrix method for solving higher order systems of differential equations of the Fuchs type. Generalized power series solution of the problem are constructed without increasing the problem dimension.
