In the context of several complex variables, we investigate the uniqueness problem for a power of a meromorphic function that shares a value with its k-th order directional derivative in ℂm. Our results extend previous uniqueness theorems from the one-variable case to higher dimensions. Furthermore, we provide numerous examples to demonstrate that our results are, in certain senses, best possible.
