Finite-Degree Predicates and Two-Variable First-Order Logic [PDF]
We consider two-variable first-order logic on finite words with a fixed number of quantifier alternations. We show that all languages with a neutral letter definable using the order and finite-degree predicates are also definable with the order predicate

Undecidability of first-order modal and intuitionistic logics with two variables and one monadic predicate letter [PDF]
We prove that the positive fragment of first-order intuitionistic logic in the language with two variables and a single monadic predicate letter, without constants and equality, is undecidable.
