Description: Closure of a projection in its subspace. If we consider this together with axpjpj 29124 to be axioms, the need for the ax-hcompl 28906 can often be avoided for the kinds of theorems we are interested in here. An interesting project is to see how far we can go by using them in place of it. In particular, we can prove the orthomodular law pjomli 29139.) (Contributed by NM, 23-Oct-1999.) (Revised by Mario Carneiro, 15-May-2014.) (New usage is discouraged.) |
