Now it makes sense to ask if the curve x(s) has a tangent at the limit point x 0 ; this is exactly the formulation of the gradient conjecture in the Riemannian case.. By the

We construct critical percolation clusters on the diamond hierarchical lattice and show that the scaling limit is a graph directed random recursive fractal.. A Dirichlet form can

In this paper we develop an elementary formula for a family of elements {˜ x[a]} a∈ Z n of the upper cluster algebra for any fixed initial seed Σ.. This family of elements

In the paper we derive rational solutions for the lattice potential modified Korteweg–de Vries equation, and Q2, Q1(δ), H3(δ), H2 and H1 in the Adler–Bobenko–Suris list.. B¨

(See [7] for a theory of the rationality of the Kontsevich integral of a knot or a boundary link.) It observes a generalisation of Casson’s formula (Equation 1) of the following
