Classical blue-shift phenomenon
Let be a finite group and let be a -periodic non-equivariant ring spectrum. The classical Tate construction is
Classical blue-shift phenomenon. The spectrum is -periodic for some positive integer . When , the -periodic ring spectrum is understood to be the contractible spectrum . The integer is called the blue-shift number. This conjecture generalizes known blue-shift and Tate-vanishing results, including the case of the group acting on connective complex K-theory; its general validity is not established.
