On the Bourgin-Yang theorem for multi-valued maps. II
The authors prove an infinite dimensional version of the Bourgin-Yang theorem: If \(\phi: S\to E_ k\) is an admissible compact field, then ind\(A(\phi)\geq k-1\). Here S and \(E_ k\) are respectively the unit sphere and a codimension k subspace of a Banach space E.Gȩba, Kazimierz, Górniewicz, Lech
