On the H\'older regularity for solutions of integro-differential equations like the anisotropic fractional Laplacian

Autor: Santos, E. B. dos, Leitão, Raimundo

In this paper we study integro-differential equations like the anisotropic fractional Laplacian. As in [Silvestre, Indiana University Mathematics Journal 55, 2006], we adapt the De Giorgi technique to achieve the $C^{\gamma}$-regularity for solutions

Crossover from mean-field to $2d$ Directed Percolation in the contact process

Autor: Santos, T. B. dos, Filho, C. I. N. Sampaio, Araújo, N. A. M., Oliveira, C. L. N., Moreira, A. A.

We study the contact process on spatially embedded networks, consisting of a regular square lattice with long-range connections. To generate the networks, a long-range connection is randomly added to each node $i$ of a square lattice, following the p

A Lightweight Regression Method to Infer Psycholinguistic Properties for Brazilian Portuguese

Autor: Santos, Leandro B. dos, Duran, Magali S., Hartmann, Nathan S., Candido Jr., Arnaldo, Paetzold, Gustavo H., Aluisio, Sandra M.

Psycholinguistic properties of words have been used in various approaches to Natural Language Processing tasks, such as text simplification and readability assessment. Most of these properties are subjective, involving costly and time-consuming surve
