Whitney Elements on Pyramids
V. GRADINARU AND R. HIPTMAIR † Abstract. Conforming finite elements inH(div; Ω) andH(curl; Ω) can be regarded as discrete differential forms (Whitney–forms). The construction of such forms is based on an interpolation idea, which boils down to a simple extension of the differential form to the interior of elements. This flexible approach can accommodate elements of more complicated shapes than ...
متن کاملPoint of Minimum Temperature
A homogeneous convex centrosymmetric body with constant thermal properties is initially at temperature zero and its boundary is maintained at a temperature Tb > 0. Prove or disprove that at any time t > 0, the point of minimum temperature is the center. Also, prove or disprove that the isothermal surfaces are convex and centrosymmetric. Note that the convexity of the isothermal surfaces will im...
متن کاملWhitney Elements on Sparse Grids
The aim of this work is to generalize the idea of the discretizations on sparse grids to discrete differential forms. The extension to general l-forms in d dimensions includes the well known Whitney elements, as well as H(div; Ω)and H(curl; Ω)-conforming mixed finite elements. The formulation of Maxwell’s equations in terms of differential forms gives a crucial hint how they should be discretiz...
متن کاملReport on Whitney Problems Workshop
Motivated by boundary value problems for partial differential equations, classical trace and extension theorems characterize traces of spaces of generalized smoothness (e.g., Sobolev, Besov, etc.) to smooth submanifolds of a Euclidean space. But in many cases one needs similar results for subsets of a more complicated geometric structure (for instance, after the change of variables initial data...
