View on Github →feat(analysis/complex/abs_max): add a version of the maximum modulus principle (#15364)
-
Add versions of the maximum modulus principle that assume strict convexity of the codomain and prove
f x = f y
instead of∥f x∥ = ∥f y∥
-
Add a version of the maximum modulus principle for arbitrary open connected sets.
-
Add supporting lemmas.
-
More lemmas about strictly convex spaces and norm (
eq_of_norm_eq_of_norm_add_eq
,same_ray.eq_of_norm_eq
,same_ray.norm_eq_iff
); -
Lemmas about
is_max_*
andλ x, ∥f x + y∥
. -
Generalize
convex.is_preconnected
fromℝ
to a real vector space.
-
-
Improve documentation.
