Extension problems in complex and CR-geometry

This book provides a survey of some aspects of extension problems in Complex Analysis and Geometry. It also includes detailed results by the author on non-compact extension: the cohomology of semi q-coronae and the unbounded boundary problem.

Presents a large survey on the broad subject of extension in complex analysis and CR geometry

Endowed with a very extensive bibliography

Klappentext

This book is both a survey of some aspects of extension problems in Complex Analysis and Geometry and a collection of results by the author. After recalling the preliminary and necessary notions of complex analysis, the survey focuses on extension of holomorphic functions (filling both compact and non-compact holes), on the reflection principle, on extension results via cohomology vanishing, and on the boundary problem. The last two subjects include detailed results by the author on non-compact extension: the cohomology of semi q-coronae and the unbounded boundary problem.
