摘要:
Some problems in the theory of approximation of complex-valued functions on locally compact Vilenkin groups in the metric of L-p, 1 <= p <= infinity, by functions with bounded spectrum, are investigated. A description of certain function spaces in terms of the best approximations are obtained and some imbedding theorems are proved.
