Query: On Tense MV-algebras   The main aim of this article is to study tense MV-algebras which are just
MV-algebras with new unary operations $G$ and $H$ which express a universal
time quantifiers. Tense MV-algebras were introduced by D. Diagonescu and G.
Georgescu. Using a new notion of an fm-function between MV-algebras we
\zruseno{will prove} \zmena{settle a half of their Open problem about
representation for some classes of tense MV-algebras, i.e., we show} that any
tense semisimple MV-algebra is induced by a time frame analogously to classical
works in this field of logic. As a by-product we obtain a new characterization
of extremal states on MV-algebras.
