Query: On a class of nonlinear elliptic, anisotropic singular perturbations
  problems   In this article we study the asymptotic behavior, of the solution of a
nonlinear elliptic, anisotropic singular perturbations problem in cylindrical
domain, the limit problem is given and strong convergences are proved, we also
give an application to intergo-differential problems.
