COALGEBRAIC APPROACH FOR PROGRAM BEHAVIOR IN COMONADS OVER TOPOSES. Autori: VALERIE NOVITZKÁ. |
||||||
Rezumat: The practical goal of program behavior studies is to enhance program and system performance. A behavior of running program can be described by evaluating the coalgebraic structure over a collection of algebraic terms on state space. Coalgebras are defined by polynomial endofunctors. We formulate the coalgebras in categories. Toposes are special kind of categories defined by axioms saying roughly that certain constructions one can make with sets can be done in a category. We use approach via toposes and comonads as dual structures to monads. In our paper we introduce the main ideas of our approach for describing the behavior of systems by coalgebras and we illustrate it on the simple examples of data structure queue. Key words and phrases. Program behavior, Category, Coalgebra, Comonad, Topos. |
