DIAZ MILLAN, REINIER. Characterization of linear functionals associated to bilinear forms of Sobolev type. Rev.colomb.mat. [online]. 2008, vol.42, n.1, pp.85-99. ISSN 0034-7426.

In this work we characterize the bilinear forms whose associated functionals vanish the multiples of (x\overline{y}-1)²ⁿ⁺¹, n = 0, 1, ..., first when they are general functionals and later on when they are hermitian. Besides we characterize the sequences of moments associated to this bilinear forms and an analog of Favards Theorem is presented.

Palabras clave : Sobolev's Product; Favard's theorem; sequence of moments..
