      rvs is (classically) equivalent to a kind of double negation
      
      Proofs showing that rvs is equivalent to a kind of step-indexed double negation modality under classical axioms. For now, placed in algebra/double_negation.v until the new directory structure is finalized.

      Prove Timeless instances in the logic instead of the model. · 0e49878b
      Robbert Krebbers authored
      Thanks to Ranald Clouston for suggesting the axiom:
      
        ▷ P ⊢ ▷ False ∨ (▷ False → P)
      
      This axiom is used to prove timeless of implication, wand and forall.
      
      Timelessness of the pure and ownM connectives is still proven in the model, but
      we first state the property in a way that it does not involved derived notions
      (like the except_last modality).

      Remove ownM_something. · 4e59a653
      Robbert Krebbers authored
      It is unused, and ownM_empty is stronger.
