Hall's universal group does not have finite big Ramsey degrees
Dragan MaÅ¡uloviÄ, Dragan Mašulović, Veljko ToljiÄ +1
In this paper we show that the Hall's universal group does not have finite big Ramsey degrees. Our strategy consists of piggybacking on the recent result of Hubička, Konečný, Todor…

Ramsey degrees: big v. small
Dragan MaÅ¡uloviÄ
In this paper we investigate algebraic properties of big Ramsey degrees in categories satisfying some mild conditions. As the first nontrivial consequence of the generalization we…

Coalgebraic methods for Ramsey degrees of unary algebras
Dragan MaÅ¡uloviÄ
In this paper we are interested in the existence of small and big Ramsey degrees of classes of finite unary algebras in arbitrary (not necessarily finite) algebraic language .…
