The book has been written in the spirit of Weierstrass. Power series play the dominant role. The treatment, being algebraic, is not restricted to complex numbers, but remains valid over any complete-valued field. This makes it applicable to situations arising fromPure and applied mathematics (Academic Press) ;14.Geometry, AnalyticGeometry, AlgebraicGeometry, Analytic.Geometry, Algebraic.516.3Abhyankar Shreeram Shankar478853MiAaPQMiAaPQMiAaPQBOOK9910816002403321Local analytic geometry925578UNINA
