Definition sieve_bounded_lattice (c : C) : bounded_lattice (sieve c). Proof. use make_bounded_lattice. - apply sieve_lattice. - apply empty_sieve. - apply maximal_sieve. - split; intros S; apply sieve_eq, funextsec; intro f; simpl. + apply (islunit_Lmax_Lbot hProp_bounded_lattice). + apply (islunit_Lmin_Ltop hProp_bounded_lattice). Defined.
