Query: Fundamental solutions to elliptic equations with discontinuous senior
  coefficients and an inequlity for these solutions   Asymptotic formula is derived for the behavior of the fundamental solution of
the second-order elliptic self-adjoint operator with a piecewise-smooth
coefficient in front of the senior derivatives near the discontinuity surface
of the coefficient. Applications to inverse problems are discussed.
