Abstract: Given a finite-dimensional Banach space $ E$ and a Euclidean norm on $ E$, we study relations between the norm and the Euclidean norm on subspaces of $ E$ of small codimension. Then for an operator taking values in a Hilbert space, we deduce an inequality for entropy numbers of the operator and its dual.
