That man lends his name, along with that of Ostap Parasyuk, to a theorem asserting that renormalized Green's functions and matrix elements of the S-matrix are free of ultraviolet divergencies.
A chess opening named for a man with this last name is a variant of the Indian Defense which, on the third move, sees Black move a bishop to B4, resulting in check. A more famous man with this last name created a theorem used in quantum field theory to construct analytic continuations of Wightman functions, known as the "edge-of-the- wedge" theorem. That man lends his name, along with that of Ostap Parasyuk, to a theorem asserting that renormalized Green's functions and matrix elements of the S-matrix are free of ultraviolet divergencies. The expectation value of the Hamiltonian is related to the Helmholtz free energy by an inequality named for him and [➤] Gibbs, and he is also the first namesake of a set of integro-differential equations used to describe the dynamics of large numbers of interacting particles that reduce to the Liouville equation for classical systems. For 10 points, identify this first namesake of the (*) BBGKY hierarchy, who also names a transformation from a unitary representation of a canonical commutation relation algebra into another unitary representation.
