COMPUTATION OF ROUGH SOLUTIONS OF ABEL INTEGRAL EQUATIONS

ABSTRACT For first and second kind Abel integral equations the problem of approximating solutions which are the sum of a Lipschitz-continuous function and a linear combination of Heaviside functions (the jump points and the heights of the jumps being unknown) is considered. It is shown that the equidistant backward Euler method converges in L1-norm as the steplength tends to zero.
