#### multiple-scales space-time analysis of a randomly perturbed one-dimensional wave-equation

(AIP Publishing, 1977-10)

An initial value problem for one_dimensional wave propagation is considered; the medium is assumed to be randomly perturbed as a function of both space and time. The stochastic perturbation theory of Papanicolaou and Keller ...

#### expansion-free electromagnetic solutions of Kerr-Schild class

(AIP Publishing, 1974-07)

Starting with the general Kerr_Schild form of the metric tensor,d s2=_+l_l (where l is null and _ is flat space_time), a study is made for those solutions of the Einstein_Maxwell equations in which l is geodesic, shear_free, ...

#### functional calculus for symmetric multigroup transport operator

(AIP Publishing, 1976-02)

A rigorous treatment of the symmetric multigroup transport equation is given by developing the functional calculus for the transport operator. Von Neumann spectral theory is applied to nonorthogonal cyclic subspaces, and ...

#### Vlasov theory of plasma oscillations: linear-approximation

(AIP Publishing, 1977)

A functional analytic approach to the linearized collisionless Vlasov equation is presented utilizing a resolvent integration technique on the resolvent of the transport operator evaluated at a particular point. Formulae ...

#### solution of multigroup transport equation in Lp spaces

(AIP Publishing, 1976-11)

The isotropic multigroup transport equation is solved in L p , p_1, for both half range and full range problems, using resolvent integration techniques. The connection between these techniques and a spectral decomposition ...

#### Case eigenfunction expansion for a conservative medium

(AIP Publishing, 1976-02)

By using the resolvent integration technique introduced by Larsen and Habetler, the one‐speed, isotropic scattering,neutron transport equation is treated in the infinite and semi‐infinite media. It is seen that the results ...

#### resolvent integration techniques for generalized transport equations

(AIP Publishing, 1979-06)

A generalized class of ’’transport type’’ equations is studied, including most of the known exactly solvable models; in particular, the transport operator K is a scalar type spectral operator. A spectral resolution for K ...

#### interaction function and lattice duals

(AIP Publishing, 1977-10)

An interaction function is defined for lattice models in statistical mechanics. A correlation function expansion is derived, giving a direct proof of the duality relations for correlation functions.

#### power statistics for wave propagation in one-dimension and comparison with radiative transport-theory. II.

(AIP Publishing, 1974-12)

We consider the one_dimensional problem of a slab having a random index of refraction and illuminated from within by a point source. We compute the expected value and the fluctuations of both the total power and power flux. ...

#### transverse plasma oscillations

(AIP Publishing, 1979)

An operator theoretic approach is used to solve the linearized Vlasov–Maxwell equations for transverse plasma oscillations. In particular, the special cases of simple and second‐order real zeros of the plasma dispersion ...
