Nuprl Lemma : grp_op_r

∀[g:GrpSig]. ∀[a,b,c:|g|].  (a * c) = (b * c) ∈ |g| supposing a = b ∈ |g|


Proof




Definitions occuring in Statement :  grp_op: *,  grp_car: |g|,  grp_sig: GrpSig,  uimplies: b supposing a,  uall: ∀[x:A]. B[x],  infix_ap: x f y,  equal: s = t ∈ T
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  uimplies: b supposing a,  prop: ℙ,  infix_ap: x f y
