Yefim Katsov, Ruvim Lipyanski, Boris Plotkin

In algebraic geometry over a variety of universal algebras $Θ$ , the group $A u t (Θ^{0})$ of automorphisms of the category $Θ^{0}$ of finitely generated free algebras of $Θ$ is of gre…

Problems in algebra inspired by universal algebraic geometry

Boris Plotkin

Let $Θ$ be a variety of algebras. In every $Θ$ and every algebra $H$ from $Θ$ one can consider algebraic geometry in $Θ$ over $H$ . We consider also a special categorical invariant…
