On uniqueness sets for an elliptic equation with constant coefficients
Ильдар Ахмедович Бикчантаев · Differential Equations · 2011
For the solutions of the elliptic equation $$ \sum\limits_{k = 0}^n {A_k \frac{{\partial ^n f}} {{\partial x^{n - k} \partial y^k }} = 0} $$ with constant coefficients, we prove a uniqueness theorem similar to the interior uniqueness theorem for analytic functions.
