LPi Logic with Fixed Point Operator
LPq algebras and Quasifields
A poster presented at Computer Science Logic and 8th Kurt Gödel Colloquium, Vienna, Austria $25^{th} – 30^{th}$ August 2003. I introduce a class of commutative $f$-rings with strong unit and with a sort of weak divisibility property, called $f$-quasifields, and show that the categories of L$\Pi_q$-algebras and of $f$-quasifields are equivalent.
Dualities for MV-algebras
This is a talk presenting dome results on geometrical dualities for MV-algebras. The article is dedicated to the memory of Leo Esakia. The talk was delivered at the Studia Logica conference Ordered Groups and Lattices in Algebraic Logic, Tbilisi, Georgia. $22^{d}$ September, 2011.
A very similar talk was selected as featured talk at the XIX Congess of Italian Mathematicians, Bologna 12-17 September 2011.
