Algebras and Representation Theory, 2020 AbstractIn this paper we introduce new affine algebraic varieties whose points correspond to associative algebras. We show that the algebras within a variety share many important homological properties. In particular, any two algebras in the same variety have the same dimension.

On Endomorphisms of Algebraic Varieties [PDF]
International Mathematics Research Notices, 2021 Abstract Consider an endomorphism of an algebraic variety over an algebraically closed field of characteristic zero that is injective on the complement of a proper closed subvariety. We prove that such an endomorphism is an automorphism, provided the morphism is quasi-finite.

Connected algebraic subgroups of groups of birational transformations not contained in a maximal one
Comptes Rendus. Mathématique, 2023 We prove that for each $n\ge 2$, there exist a ruled variety $X$ of dimension $n$ and a connected algebraic subgroup of $\mathrm{Bir}(X)$ which is not contained in a maximal one.

, 2003 We introduce the notion of a multi-fan. It is a generalization of that of a fan in the theory of toric variety in algebraic geometry. Roughly speaking a toric variety is an algebraic variety with an action of algebraic torus of the same dimension as that
