About the book
Differential Geometry: A First Course is an introduction to the classical theory of space curves and surfaces offered at the Graduate and Post- Graduate courses in Mathematics. Based on Serret-Frenet formulae, the theory of space curves is developed and concluded with a detailed discussion on fundamental existence theorem. The theory of surfaces includes the first fundamental form with local intrinsic properties, geodesics on surfaces, the second fundamental form with local non-intrinsic properties and the fundamental equations of the surface theory with several applications.
Motivation of different concepts • Outline of the methods of proofs before giving details • Simple but interesting immediate illustrations in each section after the theory • Illuminating miscellaneous examples • Illustrations of the methods of proofs of the fundamental theorems of space curves and surfaces • Exercises with hints
