摘要：

We show that the basis constant of every retractional Schauder basis on the Free space of a graph circle increases with the radius. As a consequence, there exists a uniformly discrete subset M subset of R-2 such that F(M) does not have a retractional Schauder basis. Furthermore, we show that for any net N subset of R-n, n >=( )2, there is no retractional unconditional basis on the Free space F(N).
