Comparison of Cohomological and K-theoretical Hall algebra
Felix Küng, Špela Špenko
We give a more conceptual construction of a comparison algebra morphism from the K-theoretical Hall algebra to a twist of the cohomological Hall algebra associated to a symmetric q…
Injectives obstruct Fourier-Mukai functors
Felix Küng
We use injectives as a big tilting object to obstruct liftability of exact functors to the $\dg$-level. We use the inclusion of injectives into the canonical heart as a replacement…
Algebraic for unpointed homotopy Categories
Felix Küng
We introduce the notion of Grothendieck heaps for unpointed Waldhausen categories and unpointed stable -categories. This allows an extension of the studies of $\mathrm{K}_0…
Structures on the Category of N-Complexes
Felix Küng
The theory of -complexes is a generalization of both ordinary chain complexes and graded objects. Hence it yields deeper insight in the structure of these and offers a broader r…
Algebraic K for unpointed Categories
Felix Küng
We construct a natural generalization of the Grothendieck group to the case of possibly unpointed categories admitting pushouts by using the concept of heaps recentl…
Twisted Hodge diamonds give rise to non-Fourier-Mukai functors
Felix Küng
We apply computations of twisted Hodge diamonds to construct an infinite number of non-Fourier-Mukai functors with well behaved target and source spaces. To accomplish this we firs…
