Ordered normed spaces

In this file, we define classes for fields and groups that are both normed and ordered. These are mostly useful to avoid diamonds during type class inference.

class NormedOrderedAddGroup (α : Type u_2) extends OrderedAddCommGroup , Norm , MetricSpace , AddCommGroup , PartialOrder , AddGroup , AddCommMonoid , SubNegMonoid , AddMonoid , Neg , Sub , AddCommSemigroup , AddSemigroup , AddZeroClass , Zero , AddCommMagma , Add , Preorder , LE , LT , PseudoMetricSpace , Dist : Type u_2

A NormedOrderedAddGroup is an additive group that is both a NormedAddCommGroup and an OrderedAddCommGroup. This class is necessary to avoid diamonds caused by both classes carrying their own group structure.

theorem NormedOrderedAddGroup.dist_eq {α : Type u_2} [self : NormedOrderedAddGroup α] (x : α) (y : α) : dist x y = ‖x - y‖

The distance function is induced by the norm.

class NormedOrderedGroup (α : Type u_2) extends OrderedCommGroup , Norm , MetricSpace , CommGroup , PartialOrder , Group , CommMonoid , DivInvMonoid , Monoid , Inv , Div , CommSemigroup , Semigroup , MulOneClass , One , CommMagma , Mul , Preorder , LE , LT , PseudoMetricSpace , Dist : Type u_2

A NormedOrderedGroup is a group that is both a NormedCommGroup and an OrderedCommGroup. This class is necessary to avoid diamonds caused by both classes carrying their own group structure.

theorem NormedOrderedGroup.dist_eq {α : Type u_2} [self : NormedOrderedGroup α] (x : α) (y : α) : dist x y = ‖x / y‖

The distance function is induced by the norm.

class NormedLinearOrderedAddGroup (α : Type u_2) extends LinearOrderedAddCommGroup , Norm , MetricSpace , OrderedAddCommGroup , LinearOrder , AddCommGroup , PartialOrder , AddGroup , AddCommMonoid , SubNegMonoid , AddMonoid , Neg , Sub , AddCommSemigroup , AddSemigroup , AddZeroClass , Zero , AddCommMagma , Add , Min , Max , Ord , Preorder , LE , LT , PseudoMetricSpace , Dist : Type u_2

A NormedLinearOrderedAddGroup is an additive group that is both a NormedAddCommGroup and a LinearOrderedAddCommGroup. This class is necessary to avoid diamonds caused by both classes carrying their own group structure.

theorem NormedLinearOrderedAddGroup.dist_eq {α : Type u_2} [self : NormedLinearOrderedAddGroup α] (x : α) (y : α) : dist x y = ‖x - y‖

The distance function is induced by the norm.

class NormedLinearOrderedGroup (α : Type u_2) extends LinearOrderedCommGroup , Norm , MetricSpace , OrderedCommGroup , LinearOrder , CommGroup , PartialOrder , Group , CommMonoid , DivInvMonoid , Monoid , Inv , Div , CommSemigroup , Semigroup , MulOneClass , One , CommMagma , Mul , Min , Max , Ord , Preorder , LE , LT , PseudoMetricSpace , Dist : Type u_2

A NormedLinearOrderedGroup is a group that is both a NormedCommGroup and a LinearOrderedCommGroup. This class is necessary to avoid diamonds caused by both classes carrying their own group structure.

theorem NormedLinearOrderedGroup.dist_eq {α : Type u_2} [self : NormedLinearOrderedGroup α] (x : α) (y : α) : dist x y = ‖x / y‖

The distance function is induced by the norm.

class NormedLinearOrderedField (α : Type u_2) extends LinearOrderedField , Norm , MetricSpace , LinearOrderedCommRing , Field , LinearOrderedRing , CommRing , DivisionRing , CommMonoid , StrictOrderedRing , LinearOrder , Ring , OrderedAddCommGroup , DivInvMonoid , Nontrivial , NNRatCast , RatCast , Semiring , AddCommGroup , AddGroupWithOne , NonUnitalSemiring , NonAssocSemiring , MonoidWithZero , NonUnitalNonAssocSemiring , Monoid , MulZeroOneClass , SemigroupWithZero , AddCommMonoidWithOne , CommSemigroup , Inv , Div , MulOneClass , IntCast , AddMonoidWithOne , PartialOrder , AddGroup , AddCommMonoid , Distrib , Semigroup , MulZeroClass , NatCast , SubNegMonoid , AddMonoid , One , Neg , Sub , AddCommSemigroup , AddSemigroup , AddZeroClass , CommMagma , Mul , Zero , AddCommMagma , Add , Min , Max , Ord , Preorder , LE , LT , PseudoMetricSpace , Dist : Type u_2

A NormedLinearOrderedField is a field that is both a NormedField and a LinearOrderedField. This class is necessary to avoid diamonds.

theorem NormedLinearOrderedField.dist_eq {α : Type u_2} [self : NormedLinearOrderedField α] (x : α) (y : α) : dist x y = ‖x - y‖

The distance function is induced by the norm.

theorem NormedLinearOrderedField.norm_mul' {α : Type u_2} [self : NormedLinearOrderedField α] (x : α) (y : α) : ‖x * y‖ = ‖x‖ * ‖y‖

The norm is multiplicative.
