Generalized SLE-bubble welding conjecture with a boundary insertion

At least 2 years old · documented by

Fix W1≥γ22W_1\geq\frac{\gamma^2}{2} and W>2W>2. Let BubbleH(p)\mathrm{Bubble}_{\mathbb H}(p) denote the space of bubbles in H\mathbb H rooted at pp, and let LFH(β,p)\mathrm{LF}_{\mathbb H}^{(\beta,p)} be the Liouville field measure with a boundary insertion of weight β\beta at pp. Write QD0,1(γ,βW;ℓ)\mathrm{QD}_{0,1}(\gamma,\beta_W;\ell) and QD1,1(γ,βW;ℓ)\mathrm{QD}_{1,1}(\gamma,\beta_W;\ell) for the indicated quantum disks with boundary length ℓ\ell, and let mH\mathbf m_{\mathbb H} and mH,0\mathbf m_{\mathbb H,0} be the stated Haar measures. Generalized SLE-bubble welding conjecture. There exist a σ\sigma-finite infinite measure SLEκ,pbubble(W,W1)\mathrm{SLE}^{\mathrm{bubble}}_{\kappa,p}(W,W_1) on BubbleH(p)\mathrm{Bubble}_{\mathbb H}(p) and constants C∈(0,∞)C\in(0,\infty) such that

mH⋉(∫0∞M0,2disk(W1;⋅,ℓ)×QD0,1(γ,βW;ℓ)dℓ)=C⋅LFH(β2W1+W,p)×SLEκ,pbubble(W,W1) dp,\mathbf m_{\mathbb H}\ltimes\left(\int_0^\infty\mathcal M^{\mathrm{disk}}_{0,2}(W_1;\cdot,\ell)\times\mathrm{QD}_{0,1}(\gamma,\beta_W;\ell)d\ell\right)=C\cdot\mathrm{LF}^{(\beta_{2W_1+W},p)}_{\mathbb H}\times\mathrm{SLE}_{\kappa,p}^{\mathrm{bubble}}(W,W_1)\,dp,

and, for a suitable constant C∈(0,∞)C\in(0,\infty),

mH,0⋉(∫0∞M0,2disk(W1;⋅,ℓ)×QD0,1(γ,βW;ℓ)dℓ)=C⋅LFH(β2W1+W,0)(dϕ)×SLEκ,0bubble(W,W1).\mathbf m_{\mathbb H,0}\ltimes\left(\int_0^\infty\mathcal M^{\mathrm{disk}}_{0,2}(W_1;\cdot,\ell)\times\mathrm{QD}_{0,1}(\gamma,\beta_W;\ell)d\ell\right)=C\cdot\mathrm{LF}_{\mathbb H}^{(\beta_{2W_1+W},0)}(d\phi)\times\mathrm{SLE}_{\kappa,0}^{\mathrm{bubble}}(W,W_1).

Here mH,0\mathbf m_{\mathbb H,0} is Haar measure on the conformal automorphism group of H\mathbb H fixing 00. This would generalize the paper's welding theorems to a quantum disk with one general boundary insertion. The associated bubble law is poorly understood, and the conjecture is open.
