A finite axiomatization of positive MV-algebras

Positive MV-algebras are the subreducts of MV-algebras with respect to the signature {⊕,⊙,∨,∧,0,1}\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\{\oplus , \odot , \vee , \wedge , 0, 1\}$$\end{document}. We provide a finite quasi-equational axiomatization for the class of such algebras.
