On classification of Finslerian spaces with nontrivial concircular transformations
Zohreh Fathi, Sajjad Lakzian
We prove that in a non-trivial conformal circle-preserving transformation (CPT for short), on a (forward or backward) complete Finslerian manifold , the conformal fac…
On the rigidity of Finslerian conformal circle-preserving transformations
Zohreh Fathi, Sajjad Lakzian
We prove that if a forward or backward complete Berwaldian or reversible Finslerian manifold admits a non-trivial (non-homothety) conformal concircular transformation ({\bf…
The rigidity of conformal circle-preserving transformations on Berwaldian manifolds
Zohreh Fathi, Sajjad Lakzian
We prove that a complete Berwaldian manifold admitting a nontrivial conformal circle preserving transformation (\cpt for short) must be Riemannian, provided that…
On Rigidity of ALE vector bundles
Fatemeh Asadi, Zohreh Fathi, Sajjad Lakzian
We discuss topological rigidity of vector bundles with asymptotically conical (AC) total spaces of rank greater than 1 with a sufficiently connected link; our focus will mainly be…
Discrete Ollivier-Ricci curvature
Zohreh Fathi, Sajjad Lakzian
We analyze both continuous and discrete-time Ollivier-Ricci curvatures of locally-finite weighted graphs $\G$ equipped with a given distance "$\dist$" (w.r.t. which $\G$ is metrica…
Bakry-Émery Ricci curvature of doubly warped product of weighted spaces
Zohreh Fathi, Sajjad Lakzian
We introduce a notion of doubly warped product of weighted graphs that is consistent with the doubly warped product in the Riemannian setting. We establish various discrete Bakry-É…
Time optimal control in presence of moving obstacles for a Dubins airplane
Z. Fathi, B. Bidabad, M. Najafpour
In the present work, control of time-optimal trajectory for a Dubins airplane in presence of moving and fixed obstacles is obtained. We show that for a Dubins airplane with an init…
