invertibility

The classical calculus has the property, mentioned above, of height-preserving invertibility of its logical rules.

Ketonen's proof of invertibility of the logical rules of his sequent calculus used the structural rule of cut.

By invertibility, the question of derivability is replaced by one or two equivalent questions of derivability on simpler sequents.

Chores 2009

Kleene had taken up Ketonen's calculus from the Bernays review and also treated intuitionistic sequent calculus in which invertibility is more restricted than in the classical calculus.

Would it be possible to get pointers to the fora where the battles on for example site/tree selection for temperature response, non-invertibility of tree ring temperature-response functions, and appropriateness of PCA in temperature reconstructions are being fought?

And if you do think so, then you need to show that you are aware of the problems posed by invertibility first and interactivity second.

This is a discussion about runtime rendering models versus determinate models, about how much of the imaging model can be made out to be a direct mirror of the linearised reference model / connection model, and about invertibility for pre-evaluated transforms.

That’s four problems in total, not just the one of non-invertibility.
