Overdetermined problems in the context of elliptic partial differential equations concern boundary‐value formulations in which more conditions are prescribed than are generally required for a unique ...
Elliptic boundary value problems form a central class of partial differential equations that describe steady-state phenomena in physics, engineering and geometry. In these problems, an elliptic ...
A mathematical problem solved by Susanna Heikkilä relates to the classification of quasiregularly elliptic 4-manifolds, asking what four-dimensional shapes can be obtained by deforming ...
