We investigate i.(p4 theory within the Gaussian approximation in spatially flat Robertson-Walker space in 3 + 1 dimensions. After having performed an adiabatic expansion for one of the ansatz functions we find that the renormalization of the energy-momentum tensor provides two additional constraints
Complex potentials with logarithmic singularities in their kernels are constructed for elastic bodies with a defect along a smooth arc. Muskhelishvili's conjugation is used to obtain singular integral equations of the principal boundary-value problems of plane elasticity theory. Examples are conside
