Abstract
We show that the recent result of Casta\~neda and Wu about the ramification filtration in certain -extensions of function fields of prime characteristic is equally valid over local fields of mixed characteristic . Apart from being applicable to both equicharacteristic and mixed characteristic cases, our method has the advantage of being purely local, purely conceptual, more natural, and much shorter.
