... Since the natural languages are not satisfactory to serve this purpose. It is necessary to develop the formal language called the ‘object language’. The first half of this unit concerned with the development and analysis of the object language without considering its use in the theory of inference. ...

Divide and congruence applied to eta-bisimulation
... Labelled transition systems can be distinguished from each other by a wide range of semantic equivalences, based on e.g. branching structure or decorated versions of execution sequences. Van Glabbeek [8] classified equivalences for processes that take into account the internal action τ . Here we foc ...

Sets, Logic, Relations, and Functions
... The ∴ symbol means “therefore”, and denotes the argument’s conclusion. The ∗ symbol is used to show where the premises are satisfied. We wish to distinguish between valid arguments, where the inference is always logically sound, and invalid arguments, which might lead us to infer a false conclusion. ...

On Infinitely Nested Radicals

A Simple Tableau System for the Logic of Elsewhere
... Hilbert-style proof systems but neither resolution nor tableau proof system exist for these logics. This lack is quite surprising when considering the numerous recent works related to the mechanization of modal logics in the large sense of the word (see e.g. recently [OSH95,Non95]). Using the metho ...

Existence of almost Cohen-Macaulay algebras implies the existence
... In equal characteristic, the tight closure operation has been used to present proofs of the existence of balanced big Cohen-Macaulay modules and algebras. In [2], a list of seven axioms for a closure operation is defined for finitely generated modules over a complete local domain R. Any closure oper ...
