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

Z. Bakhshandeh-Chamazkoti, A. Behzadi, R. Bakhshandeh-Chamazkoti +1

In this paper, we prove that any surface corresponding to linear second-order ODEs as a submanifold is minimal in all classes of third-order ODEs as a Riemanni…

Cartan equivalence method on fifth-order differential operator

Morteza Bakhshandeh, Rohollah Bakhshandeh-Chamazkoti, Mehdi Nadjafikhah

In this paper, we carry out the equivalence problem for fifth-order differential operators on the line under general fiber-preserving transformation using the Cartan method of equi…

Lorentz Ricci solitons of 4-dimensional non-Abelian nilpotent Lie groups

Rohollah Bakhshandeh-Chamazkoti

The goal of this paper is to investigate which one of thenon-isometric left invariant Lorentz metrics on 4-dimensional nilpotent Lie groups and satisfy…

On the invariance properties of Vaidya-Bonner geodesics via symmetry operators

Davood Farrokhi, Rohollah Bakhshandeh-Chamazkoti, Mehdi Nadjafikhah

In the present paper, we try to investigate the Noether symmetries and Lie point symmetries of the Vaidya-Bonner geodesics. Classification of one-dimensional subalgebras of Lie poi…
