Talk:Injective function

I don't like the title 'injections are invertible'. To me invertible means to have an inverse, (what the paragraph I am critisising calls a 'full inverse').

I would prefer something like 'injections have left inverses' or maybe 'injections are left-invertible'. Then the section on bijections could have 'bijections are invertible', and the section on surjections could have 'surjections have right inverses'.
