On Patched Variational Principles with Application to Elliptic and Mixed Elliptic-Hyperbolic Problems.
On some properties of solutions of transonic potential flow problems
The paper deals with solutions of transonic potential flow problems handled in the weak form or as variational inequalities. Using suitable generalized methods, which are well known for elliptic partial differential equations of the second order, some properties of these solutions are derived. A maximum principle, a comparison principle and some conclusions from both ones can be established.
