Graded q-differential algebras and algebraic models in noncommutative geometry

open access: yes, 2011
Väitekirja uurimisvaldkonnaks on diferentsiaalgeomeetria. Diferentsiaalgeomeetria keskseteks mõisteteks on koahelate kompleks ja selle kohomoloogiad. Näiteks, siledal muutkonnal on määratud diferentsiaalvormide kompleks, mille kohomoloogiad on muutkonna topoloogia analüütiliseks karakteristikuks. Kohomoloogia mõiste baseerub diferentsiaali omadusel, et

The Noncommutative Phase Space: An Algebraic Approach to Differential Geometry

open access: yes, 2016
In this thesis we will study the phase space, Ph(A), for an associative k-algebra A. The phase space can be considered as a noncommutative tangent bundle. We will derive algebraic notions of points, curves, tangent vectors and vector fields, in addition to study differentiation of vector fields, and look at what are called integrable distributions.
