A four-filtrated May spectral sequence and its applications
The authors consider an additional grading on the dual of the Steenrod algebra at an odd prime which seems closely related to the one used by \textit{H. Miller} in [Math. Proc. Camb. Philos. Soc. 84, 73--84 (1978; Zbl 0388.55013)]. Using it endows the (tri-graded) May spectral sequence with an additional grading which the authors are able to use to give an efficient way of detecting permanent cycles in the \(E_1\)-term of the May spectral sequence of low cohomological degree.
