comment “Absolute retracts” in arbitrary category
Then my question would be: is there a categorical term for the objects such that every monomorphism from them splits? I've found a purely topological definition of a closed interval, which i am satisfied with, and i was thinking about stating it in categorical terms.

comment Question concerning the proof of the equality of $x\sqrt{y}$ and $y\sqrt{\frac{x^2}{y}}$
I would say that if you are not sure if what you've done proves the conjecture, then it is not a proof, unless it happens to be a proof by pure accident.

Thank you. Do you know by any chance a French term for it? I will wait to see if there will be more answers.

Is this a standard notation? I think i have encountered $M^*$ more often.
