Abstract: | Summary Consider the Dirichlet problem for an elliptic equation in a domain , with coefficients having discontinuity on a surface . Suppose divides into 1 2(2 the inner core), the thickness of 1 is of order of magnitude , and the modulus of ellipticity in 1 is of order magnitude 1. The asymptotic behavior of the solution is studied as 0, 1 0, provided lim (/1) exists. Other questions of this type are studied both for elliptic equations and for elliptic variational inequalities.The second author is partially supported by National Science Foundation Grant 7406375 A01.
