Non-Archimedean analogue of the space of valuations on convex sets

In the last two decades a number of structures on the classical space of translation invariant valuations on convex bodies were discovered, e.g. product, convolution, a Fourier type transform. In this paper a non-Archimedean analogue of the space of such (even) valuations with similar structures is constructed. It is shown that, like in the classical case, the new space equipped with either product or convolution satisfies Poincaré duality and hard Lefschetz theorem.
