Title: Elementary differential topology
of orbifold groupoid
Abstract:We consider elementary
differential topology of orbifold groupoid (orbi-groupoid), such as the the
concept of sub-orbi-groupoid, orbi-bundles, transversality of orbifold maps,
Riemannian metric, tubular neighborhood of sub-orbi-groupoids. These properties
are very necessary and useful for studying symplectic orbi-groupoids and their
Gomov-Witten theories.
