We prove that for κ(0,8), if (η1,η2) is a 2-SLEκpair in a simply connected domain D with an analytic boundary point z0, then as r0+, P[dist(z0,ηj)<r,j=1,2] converges to a positive number for some α>0, which is called the two-curve Green’s function. The exponent α equals 12κ1 or 2(12κ1) depending on whether z0 is one of the endpoints of η1 or η2. We also find the convergence rate and the exact formula for the Green’s function up to a multiplicative constant. To derive these results, we construct two-dimensional diffusion processes and use orthogonal polynomials to obtain their transition density.
