摘要
We find a C-infinity one-parameter family of Riemannian metrics g(t) on R-3 for 0 %26lt;= t %26lt;=epsilon for some number epsilon with the following property: go is the Euclidean metric on R-3, the scalar curvatures of gt are strictly decreasing in t in the open unit ball and gt is isometric to the Euclidean metric in the complement of the ball.
