From LP formulas of the form F(T) to k -ω-regular expressions

When synthesizing a Σ-automaton specified in the language LP, the problem arises of representing the set of left-infinite words given by a formula F(t) in the form of a –ω-regular expression. Construction of this expression is based on the correspondence between structural elements of formulas and –ω-regular expressions. To ensure this correspondence, two additional operations that correspond to the quantification operations in formulas are introduced over –ω-regular sets. Methods of representation of these operations in terms of the language of –ω-regular expressions are considered. The results obtained allow to construct –ω-regular expressions for a rather wide class of LP formulas of the form F(t). © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
