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.
