Anry Nersessian (Armenian: Հանրի Ներսիսյան born 27 February 1936) is an Armenian mathematician, specializing in differential and integral equations, functional and numerical analysis. He is known for fractional derivatives introduced by the joint work with Mkhitar Djrbashian. Separately, M. Caputo considered the same modification of Riemann–Liouville integral, which is why the fractional derivative is known as Caputo, Djrbashian-Caputo or Caputo-Djrbashian derivative.
