The conjecture on Aubert-Zelevinsky involutions of ABV-packets
The conjecture on Aubert-Zelevinsky involutions of ABV-packets
Let be a reductive group over a non-Archimedean field, let be an -parameter, and let denote its ABV-packet. Let be the Pyasetskii involution of , and let denote the Aubert-Zelevinsky involution of a representation . ABV-packet involution conjecture. The Aubert-Zelevinsky involution sends the ABV-packet of to the ABV-packet of :
This is proposed as an extension of the known compatibility for local Arthur packets; the statement is presented as an expectation for ABV-packets beyond Arthur type.
