We find a full system of invariants with respect to gauge transformations L g-1 Lg for third-order hyperbolic linear partial differential operators on the plane. The operators are...
Abstract. CIRC is an automated circular coinductive prover implemented as an extension of Maude. The circular coinductive technique that forms the core of CIRC is discussed, togeth...
Specification-based testing is a particular case of black-box testing, which consists in deriving test cases from an analysis of a formal specification. We present in this paper an...
Discrete stochastic models (DSM) are widely used in various application fields today. Proxel-based simulation can outperform discrete event-based approaches in the analysis of smal...
In the previous papers [7-101we defined and explored a formal methodological framework on the basis of which resolution proof systems for strongly-finite logics can be introduced ...
Let a system of linear ordinary differential equations of the first order Y' = AY be given, where A is n x n matrix over a field F(X), assume that the degree degx(A) < d a...
We consider function fields of functions of one variable augmented by the binary operation of composition of functions. It is shown that the straightforward axiom
