Regularity for Quasi-Elliptic Pseudo-Differential Operators with Symbols in Hölder Classes
Gianluca Garello, Alessandro Morando · Birkhäuser Basel eBooks · 2008
After proving a result of continuity for pseudo-differential operators whose symbols belong to Hölder spaces and satisfy a decay of quasihomogeneous type, the authors construct a suitable symbolic calculus and a parametrrx for quasi-elliptic operators; these tools are applied to the study of quasi-elliptic linear partial differential equations with H:older coefficients.
