Singular perturbation of nonlinear systems with regular singularity
William R. P. Conti, Domingos H. U. Marchetti
We extend Balser-Kostov method of studying summability properties of a singularly perturbed inhomogeneous linear system with regular singularity at origin to nonlinear systems of t…
Hierarchical Spherical Model as a Viscosity Limit of Corresponding O(N)Heisenberg Model
William R. P. Conti, Domingos H. U. Marchetti
The O(N) Heisenberg and spherical models with interaction given by the long range hierarchical Laplacean are investigated. Two classical results are adapted. The Kac--Thompson solu…
Hierarchical Spherical Model from a Geometric Point of View
Domingos H. U. Marchetti, William R. P. Conti, Leonardo F. Guidi
A continuous version of the hierarchical spherical model at dimension d=4 is investigated. Two limit distribution of the block spin variable X^γ, normalized with exponents γ=d+2 an…
