Para-Ricci-like solitons with arbitrary potential on para-Sasaki-like Riemannian -manifolds

Hristo Manev, Mancho Manev

Para-Ricci-like solitons with arbitrary potential on para-Sasaki-like Riemannian -manifolds are introduced and studied. For the studied soliton, it is proved that its Ricci tens…
