Sufficient conditions for an entire function of exponential type to have no zeros in the open lower half-plane are found. For the first time overdetermined interpolation problems for entire functions are considered. For a wide class of convolution equations on Euclidean and symmetric spaces conditions for the hypoellipticity of solutions are obtained.
