By terms-allowed-in-types capacity, the Logic of Proofs LP includes formulas of the form t : Ï•(t), which have self-referential meanings. In this paper, “prehistoric phenomenaâ€...
In this paper we investigate the purely logical rule of term induction, i.e. induction deriving numerals instead of arbitrary terms. In this system it is not possible to bound the ...
We introduce graph reduction technology that implements functional languages with control, such as Scheme with call/cc, where continuations can be manipulated explicitly as values,...
In this paper we provide a systematic formal interpretation for most elements of the UML notation. This interpretation, in a structured temporal logic, enables precise analysis of...
In the paper we explore the idea of describing Pawlak's rough sets using three-valued logic, whereby the value t corresponds to the positive region of a set, the value f -- to...
