Ribbon dioperads and modular ribbon properads
Wai-Kit Yeung
We define and study the notions of ribbon dioperads and modular ribbon properads. We give a Lie algebra structure on the colimit total object and the limit total object of a ribbon…
A higher Hodge extension of the Feigin-Tsygan Theorem
Wai-Kit Yeung
We show that the extended noncommutative de Rham complex of a cofibrant resolution, when completed at a certain Hodge filtration, is (reduced) quasi-isomorphic to the periodic cycl…
Survey on homological flips and homological flops
Wai-Kit Yeung
We give a survey for the results in [Yeu20a, Yeu20b, Yeu20c], which attempts to relate the derived categories under general classes of flips and flops. We indicate how the approach…
Representation homology of simply connected spaces
Yuri Berest, Ajay C. Ramadoss, Wai-Kit Yeung
Let be an affine algebraic group defined over field of characteristic zero. We study the derived moduli space of G-local systems on a pointed connected CW complex X trivial…
Weight truncation for wall-crossings in birational cobordisms
Wai-Kit Yeung
We develop the technique of weight truncation in the context of wall-crossings in birational cobordisms, parallel to that in [HL15, BFK19]. More precisely, for each such wall-cross…
Grothendieck duality and Greenlees-May duality on graded rings
Wai-Kit Yeung
We formulate and prove Serre's equivalence for -graded rings. When restricted to the usual case of -graded rings, our version of Serre's equivalence also sh…
