∀ {X : Type u_1} {Y : Type u_2} [inst : PseudoEMetricSpace X] [inst_1 : PseudoEMetricSpace Y] {r : NNReal} {f : X → Y}

  HolderOnWith C₁ r f A → HolderOnWith C₂ s f A → t₁ + t₂ = 1 → HolderOnWith (C₁ ^ ↑t₁ * C₂ ^ ↑t₂) (r * t₁ + s * t₂) f A

If a function is (C₁, r)-Hölder and (C₂, s)-Hölder, then it is (C₁ ^ t₁ * C₂ ^ t₂, r * t₁ + s * t₂)-Hölder for all t₁ t₂ : ℝ≥0 such that t₁ + t₂ = 1.
