Differential Geometry of Three Dimensions - Volume 1

Differential Geometry of Three Dimensions (Volume 1) by Charles Ernest Weatherburn is a classic, fundamental treatise designed to provide students and researchers with a thorough, vector-based introduction to the differential geometry of curves and surfaces in three-dimensional Euclidean space. Originally published by Cambridge University Press, Weatherburn's work remains widely appreciated for its elegant use of vector calculus to simplify complex geometric proofs.

This textbook is extensively prescribed across BS Mathematics, MS Mathematics, M.Phil, and theoretical physics degree programs at leading Pakistani universities and colleges.

The book thoroughly covers the core principles of 3D differential geometry using vector notation. Core topics include local theory of space curves (tangent, principal normal, binormal, curvature, and torsion), the Frenet-Serret formulas, osculating sphere and osculating plane, intrinsic equations of curves, surfaces in 3D space, curvilinear coordinates and fundamental forms (first and second fundamental forms), principal curvatures, Gauss curvature, and mean curvature, lines of curvature, asymptotic lines, geodesics and geodesic curvature, and mapping of surfaces.
