Resumo:
We present an original work laying the foundations for a general theory of tensor products of a pointed metric space X with a Banach space E. Earlier papers in this direction by authors as J. D. Farmer and W. B. Johnson in Lipschitz p-summing operators and D. Cheng and B. Zheng in Lipschitz p-integral operators and Lipschitz p-nuclear operators fully justifies such an investigation. Our purpose is to develop a theory of the Lipschitz tensor product of X and E by following the original ideas of R. Schatten to construct the algebraic tensor product of two Banach spaces in his famous book A theory of cross-spaces. We are also motivated by the problem of researching the spaces of Lipschitz compact (finite-rank, approximable) operators from X to E*. It is shown that, in the study of tensor norms in a Lipschitz setting, a surprisingly large amount of ground can be covered by the analogy with the linear case. We believe that results of this type have strong potential for further applications.
