The LPi-algebras have two sets of operations and reduct to one set is an MV-algebra and to the other one is a Pi-algebra. There arise a question: which additional identities (besides those of MV-algebra and Pi-algebra) has some algebra to fulfill in order to be an LPi-algebra? In this short paper we show that under certain definition of the Pi-algebra only one identity is sufficient. However the question whether this holds for an alternative definition of the Pi-algebra seems to be interesting open problem.
Jazyk LPi-algeber se sestává z dvou množin operací, redukt LPi-algebry na první z nich je MV-algebra a na té druhé Pi-algebra. Vyvstává otázka: jaké identity (mimo těch MV- a Pi-algebraických) definují LPi-algebry. V tomto krátkém článku ukážeme, že (za určitých okolností) stačí právě jedna. Ovšem otázka, zda tento fakt platí i pro alternetivní definici Pi-algeber je zajímavým otevřeným problémem.
