Using the example of scalar and vector Wiener–Hopf equations, we consider two methods for combining the options for the Riemann integral and Lebesgue functional spaces in problems of studying and solving integral convolution equations. The method of nonlinear factorization equations and the kernel averaging method are used. A generalization of the direct Riemann integrability is introduced and applied.
Keywords: improper direct Riemann integrability, Wiener–Hopf equation, nonlinear factorization equation, kernel averaging method.
