Title: On proving consistency of equational theories in Bounded
Arithmetic
Abstract
We consider pure equational theories that allow substitution but
disallow induction, which we denote as PETS, based on recursive
definition of their function symbols. We show that the Bounded
Arithmetic theory S12 proves the consistency of PETS. Our approach
employs models for PETS based on approximate values resembling notions
from domain theory in Bounded Arithmetic, which may be of independent
interest.
