![]() | Elliptic–Hyperbolic Partial Differential Equations This text is a concise introduction to the partial differential equations which change from elliptic to hyperbolic type across a smooth hypersurface of their domain. These are becoming increasingly important in diverse sub-fields of both applied mathematics and engineering, for example: The author's research includes contributions to the mathematical theory of plasma heating in tokamaks, elliptic-hyperbolic extensions of nonlinear Hodge theory and partial differential equations in extended projective space. He is the author of the text, The Dirichlet Problem for Elliptic-Hyperbolic Equations of Keldysh Type (2012), published by Springer Berlin Heidelberg. |
