Linear Response, Bethe-Salpeter Equation, and Transport Coefficients, It is well known that the functional derivative of a single-particle Green’s function (linear response) is the same as a nonsymetrized two-particle Green’s function. This justifies the study of the Bethe-Salpeter equation.

The Description of Particles of Arbitrary Spin, makes it essential to give fresh consideration to higher-spin wave equations, which had earlier suffered from neglect as much due to fact that no higher-spin particles were then known, as due to the not-so-satisfactory nature of the theories themselves.

The relations which hold among the members of such a set of groups—called a family—are given, i.e., the relations between a group, its covering groups, and its universal covering group are established..

Linear Response, Bethe-Salpeter Equation, and Transport Coefficients,. In this paper, we wish to point out some general features of this equation and stress its applicability in constructing a linearized kinetic equation with generalized kernel and in calculating the transport coefficients. We shall limit ourselves to a self-bounded infinite system, uniform in space

The Description of Particles of Arbitrary Spin,rried on most intensively during the ‘thirties and ‘forties, and resulted in the discovery of a variety of equations with some claim to be considered as suitable for describing particles of any given spin. Since then, this field has appeared to be essentially a closed one, and it might seem inapprop
