How not to prove the Poincaré conjecture

• Published in 1966
In the collection
I have committed the sin of falsely proving Poincaré's Conjecture. But that was in another country; and besides, until now no one has known about it. Now, in hope of deterring others from making similar mistakes, I shall describe my mistaken proof. Who knows but that somehow a small change, a new interpretation, and this line of proof may be rectified!
