We consider the action of the 2-dimensional projective general linear group P GL(2, q) on the projective line P G(1, q). A subset S of P GL(2, q) is said to be an intersecting family if for every g 1 , g 2 ∈ S, there exists α ∈ P G(1, q) such that α g 1 = α g 2. It was proved by Meagher and Spiga that the intersecting families of maximum size in P GL(2, q)… (More)

Voronin’s Universality Theorem states grosso modo, that any non-vanishing analytic function can be uniformly approximated by certain shifts of the Riemann zeta-function ζ(s). However, the problem of obtaining a concrete approximants for a given function is computationally highly challenging. The present note deals with this problem, using a finite number n… (More)

We report a case of perioperative fracture-dislocation of the humeral head produced during the reaming for a resurfacing replacement hemiarthroplasty (RRH) in a 79-year old woman. This is a surgical complication not previously described in the literature for this type of prosthesis design. Resurfacing humeral head implant has been noted as a useful… (More)
