“…Writing X an for the complex analytic topological space of X, the obstruction to existence of orientations for (X, ω * X ) lies in H 2 (X an ; Z 2 ), and if the obstruction vanishes, the set of orientations is a torsor for H 1 (X an ; Z 2 ). This notion of orientation, and its analogue for 'd-critical loci', are used by Ben-Bassat, Brav, Bussi, Dupont, Joyce, Meinhardt, and Szendrői in a series of papers [2][3][4][5]21]. They use orientations on (X, ω * X ) to define natural perverse sheaves, D-modules, mixed Hodge modules, and motives on X.…”

“…We prove Theorem 1.1 using a 'Darboux Theorem' for k-shifted symplectic derived schemes by Bussi, Brav and the second author [4]. This paper is related to the series [2][3][4][5]21], mostly concerning the −1-shifted (3-Calabi-Yau) case.…”

“…Joyce etc. have a working group on the motivic DT-theory, see [14], [15]. It is interesting to see how motivic DT-invariants change under orbifold flops.…”

“…obtained by applying the renormalisation t → −r /2 t to Equation (4.4). According to [8, Section 1.1], the Hodge polynomial (more precisely, the Hodge series) of a cohomologically 6 For a cohomologically graded mixed Hodge structure , being of Tate type means that there exist integers a m ,n ∈ such that = m ,n ( ⊗n [n]) ⊕a m ,n , where = H c ( 1 , ), viewed as a pure Hodge structure of weight 2.
