Abstract

In the paper we focus upon the problem of derivability of rulesfrom rule complexes. The notion of a rule complex is the main mathematicalnotion of generalized game theory . Derivability of rules, asdefined here, comprises the concept of an extension from a default theory [9]as well as the classical notion of derivability of rules in logic. The idea oflocalness of reasoning, reasoning with a limited access to rules, is realizedby the concept of relative derivability. Starting with derivability of rules, wenext touch upon the questions of the activation of rules and consistencyof rule complexes
