The correct definition of finite elasticity: corrigendum to identification of unions
Tatsuya Motoki, Takeshi Shinohara, Keith C. Wright · Conference on Learning Theory · 1991
The paper by Wright[Wri89] contained an erroneous proof. Motoki first discovered the problem and constructed a counter-example. When this was communicated to Shinohara, who was writing a paper[Shi90] that used the erroneous result, he found a new definition which let his proof go through. Shinohara's paper did not make it clear that the definition had been changed, nor did it digress to explain the reason for the change and the status of the other results in Wright's original paper. We now set this matter straight.
