Approximating triangulated categories by spaces

Sira Gratz, Greg Stevenson

We initiate a systematic study of lattices of thick subcategories for arbitrary essentially small triangulated categories. To this end we give several examples illustrating the var…

Big categories, big spectra

Scott Balchin, Greg Stevenson

We introduce a new topological invariant of a rigidly-compactly generated tensor-triangulated category and two new notions of support. The first is based on smashing subcategories:…

Homological residue fields as comodules over coalgebras

James C. Cameron, Greg Stevenson

We explicitly present homological residue fields for tensor triangulated categories as categories of comodules in a number of examples across algebra, geometry, and topology. Our r…

Relative stable categories and birationality

Paul Balmer, Greg Stevenson

We propose a general method to construct new triangulated categories, relative stable categories, as additive quotients of a given one. This construction enhances results of Beligi…

Proper connective differential graded algebras and their geometric realizations

Theo Raedschelders, Greg Stevenson

We prove that every proper connective DG-algebra admits a geometric realization (as defined by Orlov) by a smooth projective scheme with a full exceptional collection. As a cor…

Homotopy invariants of singularity categories

Sira Gratz, Greg Stevenson

We present a method for computing -homotopy invariants of singularity categories of rings admitting suitable gradings. Using this we describe any such invariant, e.g.…
