摘要
Let f be a function defined between Banach spaces, with the property of having closed graph. If f is "uniformly directionally continuous," we will show that f is uniformly continuous. If f is linear, then f is uniformly directionally continuous and so, our result improves the classical Closed Graph Theorem. We also obtain some applications of our main results.
