Necessary and sufficient conditions for large contractions in fixed point theory
Many problems in integral and differential equations involve an equation in which there is almost a contraction mapping. Through some type of transformation we arrive at an operator of the form $H(x) =x-f(x)$. The paper contains two main parts. First we offer several transformations which yield that...
