Abstract: In this note, we reprove a theorem of Statman that deciding the fij-equality of two firstorder
typable -terms is not elementary recursive [Sta79]. The basic idea of our proof, like
that of Statman's, is the Henkin quantifier elimination procedure [Hen63]. However, our
coding is much simpler, and easy to understand.
1 Introduction
A well known theorem of Richard Statman states that if we have two -terms that are first-order
typable, deciding whether the terms reduce to the same normal form is... (Update)

...of TLC. That more expressive power is possible follows from the fact that provably hard decision problems can be embedded in TLC, see [37, 33], and that different typings allow exponentiation [19] One way of expressing all of PTIME, while avoiding the anomalies associated...
...the basic expressibility analysis in Section 3. For more details on the analysis of expressibility we refer the reader to [44, 45, 17, 37, 23, 24, 25]. The expressive power of TLC was originally analyzed in terms of computations on simply typed Church numerals (see, e.g. 4,...
