Formal Languages and Automata Theory

The ideas of and personal discussions with Zoltán Ésik were of great influence in preparing this paper. Thanks are due to two unknown referees for their helpful remarks.

Weighted omega-Restricted One Counter Automata

Let $S$ be a complete star-omega semiring and $\Sigma$ be an alphabet. For a weighted $\omega$-restricted one-counter automaton $\mathcal{C}$ with se…

In this paper we generalized the work of Heuberger and Prodinger, who derived the average protection number of plane trees, to a more general framework. We obtained the average protection number for all simply generated trees, as well as for Pólya t…

Protection numbers in simply generated trees and Pólya trees

We determine the limit of the expected value and the variance of the protection number of the root in simply generated trees, in P\'olya trees, and i…
