We prove a general stability theorem of an n-dimensional quadratic-additive type functional equation [Formula: see text]by applying the direct method.

This research paper examines the derivation and implementation of a new 4-point block method for direct integration of first-order ordinary differential equations using interpolation and collocation techniques. The approximate solution is a combination of power series and exponential function. The paper further investigates the properties of the new integrator and found it to be zero-stable, co...

in the present time, phenomenon like globalization, regionalism and economic integration are the basic issues which bring many positive consequences to the world economy. regionalism and economic integration are one of the ways that developing countries can adopt to collate the globalization process. to acknowledge their own abilities or, to settle the commercial and economic disputes in their ...
