Boundary Value Problems and Singular Pseudo-differential Operators covers the analysis of pseudo-differential operators on manifolds with conical points and edges. The standard singular integral operators on the half-axis as well as boundary value problems on smooth manifolds are treated as particular cone and wedge theories. Particular features of the book are:
* A self-contained presentation of the cone pseudo-differential calculus
* A general method for pseudo-differential analysis on manifolds with edges for arbitrary model cones in spaces with discrete and continuous asymptoties
* The presentation of the algebra of boundary value problems with the transmission property, obtained as a modification of the general wedge theory
* A new exposition of the pseudo-differential calculus with operator-valued symbols, based on twisted homogeneity as well as on parameter-dependent theories and reductions of orders.
The coverage of this book helps to enrich the general theory of partial differential equations, thus making it essential reading for researchers and practitioners in mathematics, physics and the applied sciences.

This volume contains the proceedings of the international conference on " Operator Calculus and Spectral Theory" in Lambrecht, Germany, Decem- ber 9. - 14. , 1991, sponsored by the Deutsche Forschungsgemeinschaft, and by the Karl-Weierstrass-Institute of Mathematics, Berlin. The idea was to bring together specialists from different areas of modern analysis, geometry and mathematical physics, in a similar spirit as in the earlier series of conferences of the Karl-Weierstrass- Institute (Ludwigsfelde, 1976; Reinhardsbrunn, 1985; Holzhau, 1988; Breitenbrunn,1990).

Die Theorie des NEWToNschen Potentials von Massenverteilungen im Raum ist eines der altesten Beispiele einer Verbindung von physikalischer Anschauung und mathematischer Interpretation. Bedeutende Mathematiker vieler Generationen, wie C. F. GAUSS, H. POINCARE, D. lIILEERT, N. WIENER haben daran mitgearbeitet. Die Entwicklung der modernen Potentialtheorie ist auch wesentlich durch die Arbeiten von G. C. EVANS, M. RIEsz, O. FBOSTMAN, M. V. KELDYs, M. BRELoT, H. CARTAN, J. DENY, G. CHOQUET, J. L. DooE, H. BAUER, C. CONSTANTINESCU, V. G. MAz 'JA, B. FUGLEDE und anderen bestimmt worden. Historische Darstellungen wurden z. B. in [K6], [A30], [B40] gegeben. Obwohl einige Teile der Potentialtheorie heute als im wesentlichen abgeschlossen gelten, hat sich die Entwicklung in den letzten Jahren wieder erheblich verstarkt, seit sich viele ihrer leistungsfahigen Begriffe und Methoden durch den zunehmenden Einsatz funktionalanalytischer Methoden auf weite Klassen von Problemen aus der Theorie der partiellen Differentialgleichungen anwenden lassen. Daneben sind in der Analysis auch davon unabhangige Bestrebungen von potentialtheoretischem Charakter zu beobachten.
