Query: Static Anisotropic Solutions to Einstein Equations with a Nonlocal
  Equation of State   We present a general method to obtain static anisotropic spherically
symmetric solutions, satisfying a nonlocal equation of state, from known
density profiles. This equation of state describes, at a given point, the
components of the corresponding energy-momentum tensor not only as a function
at that point, but as a functional throughout the enclosed configuration. In
order to establish the physical aceptability of the proposed static family of
solutions satisfying nonlocal equation of state,\textit{}we study the
consequences imposed by the junction and energy conditions for anisotropic
fluids in bounded matter distribution. It is shown that a general relativistic
spherically symmetric bounded distributions of matter, at least for certain
regions, could satisfy a nonlocal equation of state.
