• Apr 29, 2026 tensors mathematics of differential geometry and s: Requires choosing a connection, which may not be unique. Computations can become complex on high-dimensional manifolds. Riemann Curvature Tensor A key tensor measuring the intrinsic curvature of a manifold, defined via the covariant derivative as: \[ R(X, Y)Z = \nabla_X \nabla_Y Z - \nabla_ By Chelsie Larkin
• Jan 18, 2026 tensors differential forms and variational princip ng differential equations. Lie Derivatives: Describe how tensors and forms change along flows, essential in symmetry analysis. Noether’s Theorem: Connects symmetries of the action with conserved quantities, expressed via tensor and form language. Practical Applications an By Margarita Rau
• Aug 4, 2025 an introduction to tensors and group theory for p , satisfying four fundamental properties: closure, associativity, identity, and inverses. In physics, groups describe symmetries—transformations that leave certain properties of a system unchanged. Formal Definition: A By Sigurd Wyman
