[P:pi_term()]. (pi-rank(pirep(P)) (pi-rank(P) 1) ∈ ℕ)


Proof




Definitions occuring in Statement :  pi-rank: pi-rank(p) pirep: pirep(body) pi_term: pi_term() nat: uall: [x:A]. B[x] add: m natural_number: $n equal: t ∈ T

Latex:
\mforall{}[P:pi\_term()].  (pi-rank(pirep(P))  =  (pi-rank(P)  +  1))
