Proof step 22 from proof refine-unmap (previous step)

n < # avols[default-volid], m < # avols[default-volid], ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), default-volid ∈ avols ⊦ abs(avols[default-volid])[n] = abs(avols[default-volid][m, unmapped])[n], n = m

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 23:
m < # avols[default-volid], n < # avols[default-volid], ebm-cons(avols), ebm-vol-inv(abs(avols[default-volid])), default-volid ∈ avols ⊦ abs(avols[default-volid][n]) = abs(avols[default-volid][m, unmapped])[n], n = m

Rule argument

Additional information

Used simplifier rules: ⊦ n < # evol → abs(evol)[n] = abs(evol[n]); (s)
