Proof step 9 from proof lim-exists (previous step)

# σσ = ∞, # σσ[n] = ∞, mon(σσ) ⊦ ∃ σ1. σσ[n0] + σ1 = σσ[n], σσ = []

User applied rule insert lemma

And obtained the following new goals

Proof step 10:
mon(σσ), m ≤ n, ⌜n⌝ < # σσ ⊦ σσ[m] ⊑ σσ[n]
Proof step 11:
# σσ = ∞, # σσ[n] = ∞, mon(σσ) ⊦ n0 ≤ n ∧ ⌜n⌝ < # σσ, ∃ σ1. σσ[n0] + σ1 = σσ[n], σσ = []

Rule argument

spec: inst: name: mon-lem seq: mon(σσ), m ≤ n, ⌜n⌝ < # σσ ⊦ σσ[m] ⊑ σσ[n] subst: [σσ, m, n] → [σσ, n0, n] flags: current, []

Additional information

Used simplifier rules: prefix-def: ⊦ σ ⊑ σ0 ↔ (∃ σ1. σ + σ1 = σ0); Used terms: σσ, n0, n
