<Edward Odell> worked on the geometry of <Banach spaces>. With <Thomas Schlumprecht>, he solved the distortion problem for the classical infinite-dimensional <Hilbert space> by proving it arbitrarily distortable.<The distortion problem by Edward Odell and Thomas Schlumprecht>[Original byline and introduction]{ref}
An equivalent norm can preserve the underlying vector-space topology yet stretch unit vectors very differently inside every infinite-dimensional subspace. For any prescribed ratio greater than one, their construction forces such variation. This distinguishes topological equivalence of norms from uniform control of their geometry on large subspaces.<The distortion problem by Edward Odell and Thomas Schlumprecht>[Introduction, equation 1.1]{ref}
