Group seminorms

This file defines norms and seminorms in a group. A group seminorm is a function to the reals which is positive-semidefinite and subadditive. A norm further only maps zero to zero.

Main declarations

• AddGroupSeminorm: A function f from an additive group G to the reals that preserves zero, takes nonnegative values, is subadditive and such that f (-x) = f x for all x.
• NonarchAddGroupSeminorm: A function f from an additive group G to the reals that preserves zero, takes nonnegative values, is nonarchimedean and such that f (-x) = f x for all x.
• GroupSeminorm: A function f from a group G to the reals that sends one to zero, takes nonnegative values, is submultiplicative and such that f x⁻¹ = f x for all x.
• AddGroupNorm: A seminorm f such that f x = 0 → x = 0 for all x.
• NonarchAddGroupNorm: A nonarchimedean seminorm f such that f x = 0 → x = 0 for all x.
• GroupNorm: A seminorm f such that f x = 0 → x = 1 for all x.

Notes

The corresponding hom classes are defined in Analysis.Order.Hom.Basic to be used by absolute values.

We do not define NonarchAddGroupSeminorm as an extension of AddGroupSeminorm to avoid having a superfluous add_le' field in the resulting structure. The same applies to NonarchAddGroupNorm.

structure AddGroupSeminorm (G : Type u_7) [AddGroup G] : Type u_7

A seminorm on an additive group G is a function f : G → ℝ that preserves zero, is subadditive and such that f (-x) = f x for all x.

• toFun : G → ℝ

  The bare function of an AddGroupSeminorm.

• map_zero' : self.toFun 0 = 0

  The image of zero is zero.

  The seminorm is subadditive.

• neg' : ∀ (r : G), self.toFun (-r) = self.toFun r

  The seminorm is invariant under negation.

A seminorm on a group G is a function f : G → ℝ that sends one to zero, is submultiplicative and such that f x⁻¹ = f x for all x.

• toFun : G → ℝ

  The bare function of a GroupSeminorm.

  The image of one is zero.

  The seminorm is invariant under inversion.

structure NonarchAddGroupSeminorm (G : Type u_7) [AddGroup G] extends ZeroHom : Type u_7

A nonarchimedean seminorm on an additive group G is a function f : G → ℝ that preserves zero, is nonarchimedean and such that f (-x) = f x for all x.

• toFun : G → ℝ

• add_le_max' : ∀ (r s : G), self.toFun (r + s) ≤ max (self.toFun r) (self.toFun s)

  The seminorm applied to a sum is dominated by the maximum of the function applied to the addends.

• neg' : ∀ (r : G), self.toFun (-r) = self.toFun r

  The seminorm is invariant under negation.

NOTE: We do not define NonarchAddGroupSeminorm as an extension of AddGroupSeminorm to avoid having a superfluous add_le' field in the resulting structure. The same applies to NonarchAddGroupNorm below.
