We first give an improved lower bound for the deterministic online simulation of tapes or pushdown stores by queues. Then we inspect some proofs in a classical work on queue machines in the area of Formal Languages and outline why a main argument in the proofs is incomplete. Based on descriptional complexity, we show the intuition behind the argument to be correct.

  1. Rethinking the Role of Positional Encoding: Sliding-Window Transformers without PE Remain Turing Complete

    cs.LG 2026-06 unverdicted novelty 8.0

    Sliding-window transformers without positional encodings are Turing complete because the sliding window breaks permutation symmetry and suffices to simulate Post machines via a constant-size histogram state.
