 Title: On non-archimedean Gurarii spaces

I will present some recent results, obtained jointly with Jerzy Kakol and Wieslaw Kubis, concerning spaces of almost universal disposition for the class U_FNA of all finite-dimensional normed spaces over non-archimedean valued field K which are equipped with a non-archimedean norm. It turns out that every non-archimedean Banach space of countable type over K is of almost universal disposition for the class U_FNA if and only if K is densely valued. All non-archimedean Banach spaces of almost universal disposition for the class U_FNA are epsilon-isometric and all such spaces are isometrically isomorphic if and only if K is spherically complete and  {|t| : t \in K, t \ne 0}  = (0, \infty).
