Abstract
In this paper the authors consider equations of the form $$ \int_0^l K(x,s)u(s)ds=f(x),\quad x \in (0,l), $$ with boundary conditions $$ -\sqrt{\varepsilon}u'(0)+\beta u(0)=A,\quad u(l)=B, $$ where $A$ and $B$ are constants. \par Interpolation quadrature formulas are constructed. Difference schemes introduced according to the Shishkin scheme are used. The convergence of the method is proved and error estimates are obtained.
