Solution of a two-dimensional parabolic model problem in a degenerate angular domain [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2023
In this paper, the boundary value problem of heat conduction in a domain was considered, boundary of which changes with time, as well as there is no the problem solution domain at the initial time, that is, it degenerates into a point.

Volterra–Stieltjes integral equations and impulsive Volterra–Stieltjes integral equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
In this paper, we prove existence and uniqueness of solutions of Volterra–Stieltjes integral equations using the Henstock–Kurzweil integral. Also, we prove that these equations encompass impulsive Volterra–Stieltjes integral equations and prove the existence and uniqueness for these equations. Finally, we present some examples to illustrate our results.

Legendre wavelets technique for special Initial-Value problem for the quarter plain of heat transfer [PDF]

open access: yesMathematics and Computational Sciences, 2020
In this paper we have solved the heat transfer equation by means of the Volterra integral equation and Legendre Wavelets. Since, due to numerical facts, solution of the related partial differential equation is difficult, thus we have applied integral ...

Solution of fuzzy singular integral equation with Abel’s type kernel using a novel hybrid method

open access: yesAdvances in Difference Equations, 2020
In this paper, we are applying a novel analytical hybrid method to find the solution of a fuzzy Volterra Abel’s integral equation of the second kind. The fuzzy number is used in its parametric form under which the fuzzy Volterra Abel’s integral equation ...

Singular Volterra integral equations

open access: yesApplied Mathematics Letters, 2000
AbstractExistence results are presented for the singular Volterra integral equation y(t) = h(t) + ∫0t k(t, s) f(s, y(s)) ds, for t ∈ [0,T]. Here f may be singular at y = 0. As a consequence new results are presented for the nth order singular initial value problem.
