Instantaneously complete Ricci flows on surfaces [PDF]

The intention of this thesis is to give a survey of instantaneously complete Ricci flows on surfaces, focussing on the existence and uniqueness of its Cauchy problem.

Cohomogeneity Two Ricci Solitons with Sub-Euclidean Volume

We introduce new families of four-dimensional Ricci solitons of cohomogeneity two with volume collapsing ends. In a local presentation of the metric conformal to a product, we reduce the soliton equation to a degenerate Monge-Ampère equation for the ...

Conformal Submersions Whose Total Manifolds Admit a Ricci Soliton [PDF]

Mediterranean Journal of Mathematics, 2023
In this paper, we study conformal submersions from Ricci solitons to Riemannian manifolds with non-trivial examples. First, we study some properties of the O'Neill tensor $A$ in the case of conformal submersion. We also find a necessary and sufficient condition for conformal submersion to be totally geodesic and calculate the Ricci tensor for the total
