In this paper, we give sufficient conditions for the existence and uniqueness of solution Sturm–Liouville equations subject to Dirichlet boundary value involving Kurzweil–Henstock integrable functions on unbounded intervals. We also present a finite element method scheme functions.

The purpose of this paper is to study the validity Stokes' Theorem for singular submanifolds and differential forms with singularities in Euclidean space. results are presented context Lebesgue Integration, but their proofs involve techniques from gauge integration spirit R.~Henstock, J.~Kurzweil W.~F.~Pfeffer. We manage prove a generalized on integral currents dimension $m$ whose sets have fin...

The constructive definition usually begins with a function f, then by the process of using Riemann sums and limits, we arrive the definition of the integral of f, ∫ b a f. On the other hand, a descriptive definition starts with a primitive F satisfying certain condition(s) such as F ′ = f and F is absolutely continuous if f is Lebesgue integrable, and F is generalized absolutely continuous if f...
