Query: Quantitative $l^p$-improving for discrete spherical averages along the
  primes   We show quantitative (in terms of the radius) $l^p$-improving estimates for
the discrete spherical averages along the primes. These averaging operators
were defined by Anderson, Cook, Hughes and Kumchev and are discrete, prime
variants of Stein's spherical averages. The proof uses a precise decomposition
of the Fourier multiplier.
