An analyticity criterion and sufficient conditions for a quasianalyticity of classes of functions given on a locally "chordarc" curve (i.e. a curve, for which the ratio of the length of arc with a fixed endpoint to the length of chord subtending the arc is bounded by a number depending on the mentioned endpoint) is established. числом, що залежить від вказаного кінця).
