This category contains pages concerning Relation on Slowly Progressing Mapping which fulfils conditions of General Double Induction Principle:
Let $M$ be a class.
Let $g: M \to M$ be a slowly progressing mapping on $M$.
Let $\map \RR {x, y}$ be the relation on $M$ defined as:
- $\forall x, y \in M: \tuple {x, y} \in \R \iff x \subseteq y \lor y \subseteq x$
Then $\RR$ satisfies the conditions of the General Double Induction Principle:
- $({\text D'}_1): \quad \map \RR {x, 0}$ and $\map \RR {0, x}$ hold for every $x \in M$
- $({\text D'}_2): \quad \forall x, y \in M: \paren {\map \RR {x, y} \land \map \RR {x, \map g y} \land \map \RR {\map g x, y} } \implies \map \RR {\map g x, \map g y}$
