Asymptotic behavior of unstable perturbations of the Fubini-Study metric in Ricci flow
David Garfinkle, James Isenberg, Dan Knopf +1
Kröncke has shown that the Fubini-Study metric is an unstable generalized stationary solution of Ricci flow [Krö20]. In this paper, we carry out numerical simulations which indicat…
