# Differential Geometry: Handwritten Notes Differential geometry is a discipline of mathematics that investigates the geometry of smooth objects and spaces, sometimes known as smooth manifolds. It investigates the geometric properties of curves and surfaces using the methods of differential and integral calculus, linear algebra, and multilinear algebra. Mathematical analysis and differential geometry are related concepts. These are the lecture notes of Prof. (Rtd.) Muhammad Saleem of University of Sargodha, Sargodha.
