Abstract
The tensor charges of the nucleon are calculated in the framework of t he SU(3) chiral quark soliton model. The rotational 1/N-c and strange quark mass corrections are taken into account up to linear order. We o btain the following numerical values of the tensor charges: delta u = 1.12, delta d = -0.42, and delta s = -0.008. In contrast to the axial charges, the tensor charges in our model are closer to those of the no nrelativistic quark model, in particular, the net number of the transv ersely polarized strange quarks in a transversely polarized nucleon de lta s is compatible with zero.
