arXiv:2508.13773v3 Announce Type: replace-cross Abstract: Despite advances in the Transformer architecture, their effectiveness for long-term time series forecasting (LTSF) remains controversial. In this paper, we investigate the potential of integrating explicit periodicity modeling into the self-a
