Complete Valuations on Finite Distributive Lattices
Francesco Marigo
We characterize the finite distributive lattices which admit a complete valuation, that is bijective over a set of consecutive natural numbers, with the additional conditions of co…

Making simple proofs simpler
Pietro Codara, Ottavio M. D'Antona, Francesco Marigo +1
An open partition π [Cod09a, Cod09b] of a tree T is a partition of the vertices of T with the property that, for each block B of π, the upset of B is a union of blocks of π. This p…
