Steady-soliton limit conjecture for pluriclosed flow on Class VII+ surfaces

At least 7 years old · documented by

Let (M4,J)(M^4,J) be a compact Class VII+\mathrm{VII}_+ surface, let ω0\omega_0 be a pluriclosed metric on MM, and let p∈Mp\in M be a generic point as described in the surrounding discussion. Class VII+ soliton-limit conjecture. The solution ωt\omega_t exists on [0,∞)[0,\infty), and the pointed spaces (M,J,ωt,p)(M,J,\omega_t,p) converge in the pointed C∞C^{\infty} Cheeger–Gromov sense to a nonflat complete steady soliton (M∞,J∞,ω∞,p)(M_\infty,J_\infty,\omega_\infty,p) with smooth function f∞f_\infty, such that θ∞♯+∇f∞\theta^{\sharp}_\infty+\nabla f_\infty is J∞J_\infty-holomorphic, M∞M_\infty compactifies to (M‾∞,J‾∞)(\overline M_\infty,\overline J_\infty), and the orthogonal distribution is integrable with generic leaf whose closure is a global spherical shell. The passage presents this as a conjectural summary and gives no resolution.
