Investigate local cohomology, support theories, and associated primes within the Artin-Zhang framework of noncommutative algebraic geometry.
Constructed noncommutative spaces via base change of locally noetherian or strongly locally noetherian Grothendieck categories.
Formulated elementary objects and analyzed their injective hulls to define supports and associated primes across categorical settings.
Established spectral sequences for derived functors associated with local cohomology objects under specified conditions on elementary injective hulls.
Generalized the categorical framework to apply directly to generalized local cohomology and generalized Nagata ideal transforms.
