neura. opera.ors ha.e been explored a. surroga.e models for simula.ing physica. systems to overcome the limita.ions of tra.itiona. pa.tia. differentia. equa.ion(PDE) solvers. However, most existing opera.or lea.ning methods a.sume tha. the da.a.origina.e from a.single physica. mecha.ism, limiting their a.plica.ility a.d performance in more rea.istic scena.ios. To this end, we propose the physica. inva.ia.t a.tention neura. opera.or(PIa.O) to decipher a.d integra.e the physica. inva.ia.ts for opera.or lea.ning from the PDE series with va.ious physica. mecha.isms. PIa.O employs self-supervised lea.ning to extra.t physica. knowledge a.d a.tention mecha.isms to integra.e them into dyna.ic convolutiona. *** to existing techniques, PIa.O ca. reduce the rela.ive error by 13.6%–82.2% on PDE foreca.ting ta.ks a.ross va.ying coefficients, forces or bounda.y conditions. a.ditiona.ly, va.ied downstrea. ta.ks revea. tha. the PI embeddings deciphered by PIa.O a.ign well with the underlying inva.ia.ts in the PDE systems, verifying the physica. significa.ce of PIa.O.
