Common fixed point of a power graphic contraction pair in partial metric spaces endowed with a graph
Probabilistic Resource Analysis by Program Transformation
The aim of a probabilistic resource analysis is to derive a probability
distribution of possible resource usage for a program from a probability
distribution of its input. We present an automated multi- phase rewriting based
method to analyze programs written in a subset of C. It generates a probability
distribution of the resource usage as a possibly uncomputable expression and
then transforms it into a closed form expression using over-approximations. We
present the technique, outline the implementation and show results from
experiments with the system
On multivalued weakly Picard operators in partial Hausdorff metric spaces
We discuss multivalued weakly Picard operators on partial Hausdorff metric spaces. First, we obtain Kikkawa-Suzuki type fixed point theorems for a new type of generalized contractive conditions. Then, we prove data dependence of a fixed points set theorem. Finally, we present sufficient conditions for well-posedness of a fixed point problem. Our results generalize, complement and extend classical theorems in metric and partial metric spaces
