Abstract: Given an asymptotically conical, shrinking, gradient Ricci soliton, we show that there exists a Ricci flow solution on a closed manifold that forms a finite-time singularity modeled on the given soliton.No symmetry or Kähler assumptions on the soliton are required.The proof provides a precise asymptotic description of the singularity formation.1.
