Abstract
We find a lower estimation for the projection constant of the
projective tensor product X⊗∧Y
and the injective tensor product X⊗∨Y, we apply this
estimation on some previous results, and we also introduce a new
concept of the projection constants of operators rather than that
defined for Banach spaces.
