رفتار وابسته به انتگرال پواسون در یک سیلندر و کاربرد آن در نمایندگی توابع هارمونیک

Our first aim in this paper is to deal with asymptotic behavior of Poisson integrals in a cylinder. Next Carleman's formula for harmonic functions in it is also proved. As an application of them, we finally give the integral representation of harmonic functions in a cylinder.
