Let U be the enveloping algebra of a simple Lie algebra and let£,£'be two simple finite-dimensional U-modules.(The ground field is the complex numbers.) We give a geometric realization of the tensor product of£ and£'in terms of constructible functions and we define a semicanonical basis of this tensor product.
