            ``Carleman formula for elliptic equations with variable 
              coefficients.''

＜研究発表要旨＞
We consider the Cauchy problem for second order elliptic equations with
the Cauchy data given only on a part of the boundary of the domain. We 
derive a Carleman type formula for solutions to this problem and give a
conditional stability estimate. (joint work with E.Arbuzov)
