摘要：

We consider the problem of representation of bivariate functions by sums of ridge functions. It is shown that if a function from a certain class of smoothness is represented by the sum of finitely many ridge functions with arbitrary behaviors, then it can be also represented as the sum of ridge functions of the same class of smoothness. As an example, this result is applied to a homogeneous partial differential equation with constant coefficients.
