Linear Algebra Problems Solved by Using Damped Dynamical Systems on the Stiefel Manifold
M Gulliksson, A Oleynik, M Ogren +1
We develop a new method for solving minimization problems on the Stiefel Manifold using damped dynamical systems. The constraints are satisfied in the limit by an additional damped…
Lie symmetries reduction and spectral methods on the fractional two-dimensional heat equation
Rohollah Bakhshandeh-Chamazkoti, Mohsen Alipour
In this paper, the Lie symmetry analysis is proposed for a space-time convection-diffusion fractional differential equations with the Riemann-Liouville derivative by (2+1) independ…
Geometry of submanifolds of all classes of third-order ODEs as a Riemannian manifold
