Popis:	We give a new scale of completeness conditions for exponential systems in two types of functional spaces on subsets of the complex plane. The first is the Banach spaces of functions that are continuous on a compact and simultaneously holomorphic in the interior of this compact, if this interior is nonempty, with a uniform norm. The second is the spaces of holomorphic functions on a bounded open set with a topology of uniform convergence on compacts. These conditions are formulated in terms of the perimeter of the convex hull of the domain of determining of functions from space and new characteristics of distribution of exponents of exponential system.
