On a Theorem of Razborov

In an unpublished Russian manuscript Razborov proved that a matrix family with high
rigidity over a finite field would yield a language outside the polynomial hierarchy
in communication complexity.

We present an alternative proof that strengthens the original result in several ways.
In particular, we replace rigidity by the strictly ... more >>>
