Bobbie Ann Austin,Ami D. GadhiaWe define a . as a surface . whose boundary components have been matched in pairs in such a way that . as well as its unit normal . are continuous across the boundary. This allows us to prove an analog of the fact that the tangent winding number of a closed plane curve is an integer.
