On a weak uniqueness for some elliptic equations
M. V. Safonov · Communications in Partial Differential Equations · 1994
Uniqueness is proved to the Dirichlet problem for second order uniformly elliptic nondivergence equations. The coefficients of second derivatives are supposed to be continous except for a closed set having zero Hausdorff measure corresponding to the function h(s)=s α for some α>
