Abstract
In this paper, we are interested in studying when an element in the projective tensor product turns out to be a Daugavet point. We prove first that, under some hypothesis, the assumption of having the Daugavet property implies the existence of a great amount of isometries from into . Having this in mind, we provide methods for constructing non-trivial Daugavet points in . We show that -spaces are examples of Banach spaces such that the set of the Daugavet points in is weakly dense when is a subspace of . Finally, we present some natural results on when an elementary tensor is a Daugavet point.
