Abstract (in Japanese) (See Japanese page) 
(in English) To apply Logically Constrained Term Rewrite Systems (LCTRSs, for short) to program verification, a previous work targets programs that are executed sequentially. Considering actual usage of computers, it has been expected to develop a verification method for equivalence between sequentially executed programs and their concurrent versions. In this paper, we propose a transformation of programs with exclusive control based on semaphores into LCTRSs, aiming at modeling concurrent programs by LCTRSs. To this end, we first expand arguments of a function symbol that has been introduced to represent a configuration of sequential execution, so as to store all executed processes. Next, we show how to represent operations for semaphores by rewrite rules, and show a transformation of programs with exclusive control based on semaphores into LCTRSs. We manage waiting lists for semaphores by means of number checks, avoiding recursive data structures such as lists.
