Function spaces, approximations, and differential equations. Collected papers dedicated to Oleg Vladimirovich Besov on his 70th birthday. Transl. from the Russian. Moscow: Maik Nauka/Interperiodika. Proceedings of the Steklov Institute of Mathematics 243, 154-184 (2003); translation from Tr. Mat. Inst. Steklova 243, 161-193 (2003).
Summary: For isotropic Calderon-type spaces and generalized Besov spaces, criteria for embeddings into rearrangement invariant spaces are established, sharp estimates for decreasing rearrangements are found, and optimal rearrangement invariant spaces are described.
For the entire collection see [Zbl 1064.46002].
