Holomorphic Function Theory in Several Variables : An Introduction This book provides an introduction to complex analysis in several variables. The viewpoint of integral representation theory together with Grauerts bumping method offers a natural extension of single variable techniques to several variables analysis and leads rapidly to important global results. Applications focus on global extension problems for CR functions such as the Hartogs Bochner phenomenon and removable singularities for CR functions. Three appendices on differential manifolds sheaf theory and functional analysis make the book self contained. Each chapter begins with a detailed abstract clearly demonstrating the structure and relations of following chapters. New concepts are clearly defined and theorems and propositions are proved in detail. Historical notes are also provided at the end of each chapter. Clear and succinct this book will appeal to post graduate students young researchers seeking an introduction to holomorphic function theory in several variables and lecturers seeking a concise book on the subject.
