Anry Nersessian (Armenian: Անրի Ներսեսյան 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, that's why the fractional derivative is known as Caputo, Djrbashian-Caputo or Caputo-Djrbashian derivative.

Education and career
Nersessian matriculated at Yerevan State University (YSU) in 1952 and graduated in 1957. From 1958 to 1961 he was a post graduate student of the Institute of Mathematics of National Academy of Sciences of Armenia. In 1961 he received his Ph.D. (Russian candidate degree) from Steklov Institute of Mathematics with thesis Expanding of Eigenfunctions of Some Problems for Differential Equations with Retarded Argument. In 1976 he received his doctorate degree (Russian doctorate beyond the Ph.D.) with thesis Cauchy Problem for Weakly Hyperbolic Equations from Institute of Mathematics, Ukrainian Academy of Sciences. He was head of the department of higher mathematics and mathematical physics of Yerevan State University from 1970 to 1979. Since 1979, he is heading the Department of Differential and Integral Equations at the Institute of Mathematics.
Nersessian supervised 30 Ph.D. theses on differential equations, functional analysis and numerical analysis.
