• Hipoelipticidade global de campos vetoriais no toro TN 

      Nascimento, Moisés Aparecido do (Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Matemática, 2010-06-21)
      In this work, we will see that if the transpose operator of a smooth real vector field L defined on the N-dimensional torus, regarded as a linear differential operator with coefficients in C1(TN), is globally hypoelliptic, ...

      The main aim of this work is to study necessary and sufficient conditions for a distribution, whose compact support is contained in a hyperplane, to be in the local Hardy space hp(Rn).
    • Operadores de Calderón-Zygmund e o teorema T1 

      Prado, Roxana Bedoya; http://lattes.cnpq.br/3922967559943315 (Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Matemática, 2009-04-14)
      In this work, we present necessary and suficient conditions for that an operator of Calderón-Zygmund type can be extended to a bounded operator on L2. By using results of interpolation and cancellation conditions on the ...
    • Hipoelipticidade, resolubilidade e formas normais para campos vetoriais no toro 

      Rampazo, Patrícia Yukari Sato; http://lattes.cnpq.br/9047808021065602 (Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em MatemáticaCâmpus São Carlos, 2015-04-24)
      The main aim of this work is to study a class of real vector elds de ned on a torus, where the concepts of global hypoellipticity, global C1 solvability and reduction to its normal form are equivalents. We also study a ...
