| Abstract | |
We consider the Cauchy problem for the Helmholtz equation with variable coefficient. Under (pseudo) convexity type conditions we show that stability in this problem is improving when frequency (wave number) increases. In proofs we use Carleman estimates for the wave equation and special partitioning of the unity. We discuss similar questions for control theory and inverse problems. |
