Adaptively-refinable polar-spline discrete differential forms: hierarchical construction, exactness, and applications
A common approach to representing disk-like and sphere-like geometries in isogeometric analysis is to use collapsed-edge singularities in the underlying parameterization. The resulting tensor-product B-spline spaces on such singular parameterizations lack the required smoothness to be used in isogeometric analysis. Pol...
