Kernekoncepter
Fubini-Study metric perturbations lead to local singularities in Ricci flow.
Statistik
Kr¨oncke has shown that the Fubini–Study metric is an unstable generalized stationary solution of Ricci flow [Kr¨o20].
In his dissertation, Kr¨oncke computes the third variation of Perelman’s entropy to prove the surprising result that Fubini–Study is in fact unstable. This calculation has appeared as [Kr¨o20] and has been independently verified in [KˇS19].
Citater
"Unstable perturbations studied here all lie outside the space of K¨ahler initial data."
"The blowdown soliton is unique among K¨ahler solitons."
