Trees over Infinite Structures and Path Logics with Synchronization [PDF]
We provide decidability and undecidability results on the model-checking problem for infinite tree structures. These tree structures are built from sequences of elements of infinite relational structures.

Equivalence Problems for Tree Transducers: A Brief Survey [PDF]
The decidability of equivalence for three important classes of tree transducers is discussed. Each class can be obtained as a natural restriction of deterministic macro tree transducers (MTTs): (1) no context parameters, i.e., top-down tree transducers, (

On decidability of pure hybrid logic
In this paper we study a decidable class of pure Hybrid Logic. To prove decidability we use terminating sequent for formulae of H(@) logic.

A dependent nominal type theory [PDF]
Nominal abstract syntax is an approach to representing names and binding pioneered by Gabbay and Pitts. So far nominal techniques have mostly been studied using classical logic or model theory, not type theory. Nominal extensions to simple, dependent and

An analytical method for well-formed workflow/Petri net verification of classical soundness
In this paper we consider workflow nets as dynamical systems governed by ordinary difference equations described by a particular class of Petri nets. Workflow nets are a formal model of business processes.

To the 90th anniversary of the birth of A. I. Kokorin. Stages of scientific and pedagogical way
The paper is devoted to the scientific and pedagogical activity of A. I. Kokorin, the founder of the Irkutsk algebraic-logical school, whose 90th anniversary is celebrated in November 2019. Five research areas with the most significant contributions made

Decidability of Intelligent Systems [PDF]
Intelligent systems are designed on the model of the operation of mind; but they come across, at least, the following problems: (a) Can IS solve every problem?

Trace Refinement in Labelled Markov Decision Processes [PDF]
Given two labelled Markov decision processes (MDPs), the trace-refinement problem asks whether for all strategies of the first MDP there exists a strategy of the second MDP such that the induced labelled Markov chains are trace-equivalent.

Universality and Almost Decidability [PDF]
We present and study new definitions of universal and programmable universal unary functions and consider a new simplicity criterion: almost decidability of the halting set. A set of positive integers S is almost decidable if there exists a decidable and generic (i.e. a set of natural density one) set whose intersection with S is decidable.

What decides the direction of a current? [PDF]
Nonequilibria show currents that are maintained as the result of a steady driving. We ask here what decides their direction. It is not only the second law, or the positivity of the entropy production that decides; also non-dissipative aspects often matter and sometimes completely decide.
