{synonym}
The Wiener-Hopf method solves a <boundary value problem> with complementary half-line traces by <Wiener-Hopf factorization> and additive splitting into upper- and lower-half-plane analytic functions. Analytic continuation gives a common entire function, whose growth and edge conditions determine its admissible value.
