An extremal subharmonic function in non-archimedean potential theory
Małgorzata Stawiska
We define an analog of the Leja-Siciak-Zaharjuta subharmonic extremal function for a proper subset of the Berkovich projective line over a field with a non-archimedean ab…

Some approximation problems in semi-algebraic geometry
Shmuel Friedland, Malgorzata Stawiska
In this paper we deal with a best approximation of a vector with respect to a closed semi-algebraic set in the space endowed with a semi-algebraic norm . Unde…

Best approximation on semi-algebraic sets and k-border rank approximation of symmetric tensors
Shmuel Friedland, Malgorzata Stawiska
In the first part of this paper we study a best approximation of a vector in Euclidean space R^n with respect to a closed semi-algebraic set C and a given semi-algebraic norm. Assu…
