Retractions of free MV-algebras and unital -groups
L. M. Cabrer, D. Mundici
A number of papers deal with the problem of counting the number of retractions of a structure onto a substructure In the particular case when is a free algebra, this n…
Hopfian -groups, MV-algebras and AF C-algebras
Daniele Mundici
An algebra is said to be hopfian if it is not isomorphic to a proper quotient of itself. We describe several classes of hopfian and of non-hopfian unital lattice-ordered abelian gr…
The Euler valuation on MV-algebras
Daniele Mundici, Andrea Pedrini
Every finitely presented MV-algebra A has a unique idempotent valuation E assigning value 1 to every basic element of A. For each element a of A, E(a) turns out to coincide with th…
Severi-Bouligand tangents, Frenet frames and Riesz spaces
Leonardo Manuel Cabrer, Daniele Mundici
It was recently proved that a compact set has an outgoing Severi-Bouligand tangent vector at iff some principal ideal of the Riesz space…
