  • Approximation of locally integrable functions on the real line 
    Stepanets, O.I.; Wang Kunyang; Zhang Xirong (Український математичний журнал, 1999)
    We introduce the notion of generalized ψ¯ -derivatives for functions locally integrable on the real axis and investigate problems of approximation of the classes of functions determined by these derivatives with the use ...
