Consider a compact symplectic sub-orbifold groupoid $\sf S$ of a compact symplectic orbifold groupoid $(\mathsf X,\omega)$. Let $\mathsf X_{\mathfrak a}$ be the weight-$\mathfrak a$ blowup of $\sf X$ along $\sf S$, and $\mathsf D_{\mathfrak a}=\maths

Comparing to the construction of stringy cohomology ring of equivariant stable almost complex manifolds and its relation with the Chen-Ruan cohomology ring of the quotient almost complex orbifolds, the authors construct in this note a Chen-Ruan cohom

In this paper, motivated by Chen–Ruan’s stringy orbifold theory on almost complex orbifolds, we construct a new equivariant cohomology ring $${\mathscr {H}}^*_G(X)$$ for an equivariant almost complex pair (X, G), where X is a compact connected al

Let $$\mathsf {X}$$ be a compact symplectic orbifold groupoid with $$\mathsf {S}$$ being a compact symplectic sub-orbifold groupoid, and $${\underline{\mathsf {X}}_{\mathfrak {a}}}$$ be the weight- $${\mathfrak {a}}$$ blowup of $$\mathsf {X}$$ along

It was proved by Fan--Lee and Fan that the absolute Gromov--Witten invariants of two projective bundles $\mathbb P(V_i)\rightarrow X$ are identified canonically when the total Chern classes $c(V_1)=c(V_2)$ for two bundles $V_1$ and $V_2$ over a smoot

Let X : = [ M / G ] be a compact orbifold given by the quotient of a connected compact Lie group G action on an oriented smooth closed manifold M, where the action is assumed to be smooth, effective, locally free and orientation preserving. Let f ¯
As groupoids generalize groups, motivated by group extensions we consider a kind of fibrations of Lie groupoids, called locally topological product Lie groupoid fibrations with fiber $\sf A$, i.e., \[ 1\rightarrow {\sf A} \rightarrow {\sf G} \rightar
