    In this paper we are concerned with nonlinear reaction-diffusion equations posed in a time-dependent family of domains {Omega(epsilon)(t)}(t is an element of R) subset of Rn+1 which collapses to a lower dimensional set as ...
  • Geometrically uniform hyperbolic codes

    Lazari, Henrique Autor UNESP; Palazzo, Reginado (Computational & Applied Mathematics, 2005) [Artigo]
    In this paper we generalize the concept of geometrically uniform codes, formerly employed in Euclidean spaces, to hyperbolic spaces. We also show a characterization of generalized coset codes through the concept of G-linear codes.
