ON THE CONVERSE THEOREM OF APPROXIMATION IN VARIOUS METRICS FOR NONPERIODIC FUNCTIONSMilos TomicAbstract: The modulus of smoothness in the norm of space $L_q$ of nonperiodic functions of several variables is estimated by best approximations by entire functions of exponential type in the metric of space $L_p$, $1\leq p\leq q<\infty$.
