A boundary-value problem with nonlocal integral condition of Samarskii–Ionkin type is studied for a mixed-type equation with singular coefficients in a rectangular domain. A uniqueness criterion for the problem is established by the method of spectral analysis.
Keywords: mixed-type equation, nonlocal integral condition.
Mots-clés : singular coefficient
