| ABSTRACT: |
We consider the supergravity backgrounds that correspond to
supersymmetric Wilson line operators in the context of AdS/CFT
correspondence. Supersymmetric Wilson lines in N=4 U(N) Yang-Mills
theory are labeled by Young diagrams. So one can expect that there are
supersymmetric solution of IIB supergravity labeled by Young diagrams.
We study the gravitino and dilatino conditions under the appropriate
anzats, and obtain some necessary conditions for a supergravity background
that preserves the same symmetry as the supersymmetric Wilson lines.
The supergravity solutions are characterized by continuous version
of Maya diagrams.
