Tree Languages Defined in First-Order Logic with One Quantifier Alternation
We study tree languages that can be defined in 2. These are tree languages definable by a first-order formula whose quantifier prefix is , and simultaneously by a first-order for...

On n-contractive fuzzy logics
It is well known that MTL satisfies the finite embeddability property. Thus MTL is complete w.r.t. the class of all finite MTL-chains. In order to reach a deeper understanding ...
