Wall-crossing for equivariant DT4 invariants
Arkadij Bojko, Nikolas Kuhn, Henry Liu +1
We prove the wall-crossing formula conjectured by Gross--Joyce--Tanaka for equivariant enumerative invariants of CY4 categories equipped with framing functors. We also establish a…

Wall-crossing for invariants of equivariant 3CY categories
Nikolas Kuhn, Henry Liu, Felix Thimm
We provide a wall-crossing framework for operational enumerative invariants of equivariant 3-Calabi--Yau categories arising from virtual cycles. The strategy follows ideas of Joyce…

K-Theoretic Donaldson-Thomas Theory of and Factorization
Felix Thimm
We compute the equivariant K-theoretic Donaldson--Thomas invariants of using factorization and rigidity techniques. For this, we develop a ge…
