BddDistributiveLattice ∈ SmallCategory'
Proof
Definitions occuring in Statement :
distributive-lattice-cat: BddDistributiveLattice,
small-category: SmallCategory,
member: t ∈ T
Definitions unfolded in proof :
distributive-lattice-cat: BddDistributiveLattice,
member: t ∈ T,
uall: ∀[x:A]. B[x],
so_lambda: λ2x y.t[x; y],
bdd-distributive-lattice: BoundedDistributiveLattice,
subtype_rel: A ⊆r B,
so_apply: x[s1;s2],
so_lambda: λ2x.t[x],
so_apply: x[s],
so_lambda: so_lambda5,
so_apply: x[s1;s2;s3;s4;s5],
uimplies: b supposing a,
all: ∀x:A. B[x],
and: P ∧ Q,
cand: A c∧ B,
compose: f o g,
squash: ↓T,
true: True,
guard: {T},
iff: P ⇐⇒ Q,
