Moduli of Continuity and Global Smoothness Preservation
Av George A. Anastassiou, Sorin G. Gal
Inbunden, 1999
1096 kr
Lägg i varukorg
We study in Part I of this monograph the computational aspect of almost all moduli of continuity over wide classes of functions exploiting some of their convexity properties. To our knowledge it is the first time the entire calculus of moduli of smoothness has been included in a book. We then …
