Varieties over Special Fields [PDF]

open access: yes, 2005
In the previous chapter we dealt with algebraic and geometric objects over arbitrary fields. In this chapter we explain additional properties of these objects when considered over special fields. We concentrate on varieties over the complex numbers and finite fields.

On the Geometry of Some Special Projective Varieties

Lecture Notes of the Unione Matematica Italiana, 2016
Providing an introduction to both classical and modern techniques in projective algebraic geometry, this monograph treats the geometrical properties of varieties embedded in projective spaces, their secant and tangent lines, the behavior of tangent linear spaces, the algebro-geometric and topological obstructions to their embedding into smaller ...

Special reflexive graphs in modular varieties [PDF]

open access: yesAlgebra Universalis, 2004
We investigate a special kind of reflexive graph in any congruence modular variety. When the variety is Maltsev these special reflexive graphs are exactly the internal groupoids, when the variety is distributive they are the internal reflexive relations.

On special amalgams and closed varieties of posemigroups

2022
Summary: In this paper we extend a result of \textit{H. E. Scheiblich} [Semigroup Forum 13, 103--114 (1976; Zbl 0355.20071)] by showing that variety of po-normal bands is closed. We also extend the well known results to posemigroups namely, that pogroups and inverse posemigroups have special amalgamation property in the category of all posemigroups and
