Comment (by darij):
Every lambda-ring canonically has Adams operations defined on it (
https://www.encyclopediaofmath.org/index.php/Lambda-ring ). The symmetric
functions have a canonical lambda-ring structure. (There is yet another
one on their homogeneous components, but I'm talking about the one on the
whole ring.) The Adams operations of this lambda-ring structure are the
Frobenius operators. This is in Hazewinkel's various texts.
I think there are good reasons for Aguiar and Lauve calling their
operators "Adams operators", but I don't think these reasons come from
lambda-ring theory.
