We give an axiomatic treatment of fixed-point operators in categories. A notion of iteration operator is defined, embodying the equational properties of iteration theories. We p...
ELAN implements computational systems, a concept that combines two first class entities: rewrite rules and rewriting strategies. ELAN can be used either as a logical framework or ...
—Space-filling layout techniques for tree representations are frequently used when the available screen space is small or the data set is large. In this paper, we propose an ef...
- We develop a numerical scheme for computing the solution of a generalized version of Fisher's equation. The main idea is to use a modi ed Crank-Nicolson method in order to c...
