On tangential weak defectiveness and identifiability of projective varieties

A point $p\in\mathbb{P}^N$ of a projective space is $h$-identifiable, with respect to variety $X\subset\mathbb{P}^N$, if it can be written as linear combination $h$ elements $X$ in unique way. Identifiability implied by conditions on the contact locus general spaces called non weak defectiveness and tangential defectiveness. We give ensuring an irreducible non-degenerated we apply these results Segre-Veronese varieties.
