Abstract

This thesis concerns some interactions between algebraic geometry and noncommutative
algebra in a categorical language. This interplay allows noncommutative
constructions of geometric motivation and we explore their structure.
In chapters 1 and 2 we survey the main ideas, contextualising this area and
introducing the main concepts and results used later in the thesis. These include
Morita theory for derived categories, tilting t-structures with respect to torsion
theories and generalities on noncommutative projective geometry.
Chapter 3 is devoted to prove that, under certain conditions, mutations for
quivers with potentials induce derived equivalences on the corresponding Jacobian
algebras. We give examples of such Jacobian algebras and show how they occur
naturally in geometry.
In chapter 4 we turn our attention to to a class of skew-polynomial algebras
and explore ways of classifying their noncommutative projective geometry, studying
graded Morita equivalences, point varieties and birational equivalences.
Finally, chapter 5 contains an algebraic description of perverse coherent
t-structures for the derived category of coherent sheaves on a complex projective
variety. Furthermore we define analogous structures in adequate noncommutative
settings.
