Abstract
Polynomial spline spaces defined on mixed meshes consisting of triangles and rectangles are studied for the C 0 case. These include triangulations with hanging vertices as well as T-meshes. In addition to dimension formulae, explicit basis functions are constructed, and their supports and stability are discussed. The approximation power of the spaces is also treated.
