Algebra
The research in the area of Algebra covers themes in the subareas of Algebraic Geometry, Number Theory, Theory of Representations of Algebras, Theory of Group Algebras and Theory of Codes.
Some problems addressed are: in Theory of Representations of Algebras, Hochschild cohomology, Igusa-Todorov function, derived category, Auslander-Reiten theory for triangular categories; in Group Algebra Theory, applications to error correction codes; in Algebraic Geometry Max Noether’s theorem for non-hyperelitic integral curves and singular rational curves: dimension and weight via semigroups of values are studied. In Number Theory, the focus is on Diophantine equations and zero-sum problems.
