Application de la théorie des noyaux positifs à l'estimation des processus et aux champs markoviens
We characterize the Hunt convolution kernels on () whose the Green type kernels on ; ,
Let , denote the space of Bessel potentials , , with norm . For integer can be identified with the Sobolev space .One can associate a potential theory to these spaces much in the same way as classical potential theory is associated to the space , and a considerable part of the theory was carried over to this more general context around 1970. There were difficulties extending the theory of thin sets, however. By means of a new inequality, which characterizes the positive cone in the space...
