∀[E:Type]. ∀[cmp:comparison(E)]. ∀[tr:bs_tree(E)].  (bs_tree_ordered(E;cmp;tr) ∈ ℙ)


Proof




Definitions occuring in Statement :  bs_tree_ordered: bs_tree_ordered(E;cmp;tr),  bs_tree: bs_tree(E),  comparison: comparison(T),  uall: ∀[x:A]. B[x],  prop: ℙ,  member: t ∈ T,  universe: Type
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  bs_tree_ordered: bs_tree_ordered(E;cmp;tr),  prop: ℙ,  so_lambda: λ2x.t[x],  so_apply: x[s],  so_lambda: so_lambda(x,y,z,w,v.t[x; y; z; w; v]),  and: P ∧ Q,  implies: P ⇒ Q,  comparison: comparison(T),  all: ∀x:A. B[x],  so_apply: x[s1;s2;s3;s4;s5]
