Abstract:
It is shown that if the operator $\left ( {Lx} \right )\left ( t \right ) = \dot x\left ( t \right ) - A\left ( t \right )x\left ( t \right )$ is semi-Fredholm, then the differential equation $\dot x = A\left ( t \right )x$ has an exponential dichotomy on both $[0,\infty )$ and $( - \infty ,0]$. This gives a converse to an earlier result.References
