(α : Type u_1) → [Mul α] → [Zero α] → [Preorder α] → Prop

Typeclass for strict reverse monotonicity of multiplication by nonnegative elements on the left, namely b * a₁ < b * a₂ → a₁ < a₂ if 0 ≤ b. You should usually not use this very granular typeclass directly, but rather a typeclass like IsStrictOrderedRing.
