Reliable and efficient a posteriori error estimation for adaptive IGA boundary element methods for weakly-singular integral equations. [PDF]

open access: yesComput Methods Appl Mech Eng, 2015
We consider the Galerkin boundary element method (BEM) for weakly-singular integral equations of the first-kind in 2D. We analyze some residual-type a posteriori error estimator which provides a lower as well as an upper bound for the unknown Galerkin ...

Solutions for singular Volterra integral equations [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2009
We consider the system of Volterra integral equations $$ \begin{array}{l} u_i(t)=\int_{0}^{t}g_i(t,s)[P_i(s,u_1(s),u_2(s),\cdots, u_n(s)) + Q_i(s,u_1(s),u_2(s),\cdots, u_n(s))]ds, t\in [0,T],1\leq i\leq n \end{array} $$ where $T>0$ is fixed and the ...

A Regularization of Fredholm type singular integral equations [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We present a method to regularize first and second kind integral equations of Fredholm type with singular kernel. By appropriate application of the Poincaré-Bertrand formula we change such integral equations into a second kind Fredholm's integral ...

Approximate methods for solving degenerate singular integral equations

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки, 2023
Background. Singular integral equations in degenerate cases describe many processes in natural science and technology. The theory of these equations has been studied quite well, but as far as the authors know, there are currently no analytical methods ...

Approximate solution of singular integral equations

open access: yesApplied Mathematics Letters, 2004
An approximate method is developed for solving singular integral equations of the first kind, over a finite interval. The singularity is assumed to be of the Cauchy type, and the four basically different cases of singular integral equations of practical ...

Some new explicit bounds for weakly singular integral inequalities with applications to fractional differential and integral equations

open access: yesJournal of Mathematical Analysis and Applications, 2008
Some new weakly singular integral inequalities of Gronwall–Bellman type are established, which generalized some known weakly singular inequalities and can be used in the analysis of various problems in the theory of certain classes of differential ...
