    • We show that the product of any sphere by any compact connected component of a real algebraic variety is Nash isomorphic to a real algebraic variety and we deduce such a result for some non-compact components too. It follows also that the product of any sphere by any compact global Nash subvariety of $\mathbb R^n$ is Nash isomorphic to a real algebraic variety.

    Abstract: We show that the product of any sphere by any compact connected component of a real algebraic variety is Nash isomorphic to a real algebraic variety and we deduce such a result for some non-compact components too. It follows also that the product of any sphere by any compact global Nash subvariety of $\mathbb R^n$ is Nash isomorphic to a real algebraic variety.
