The Pa­cific Journ­al of Math­em­at­ics has pub­lished high-qual­ity math­em­at­ic­al re­search in a broad range of math­em­at­ic­al sub­jects since 1951. PJM pub­lishes art­icles at low cost to lib­rar­ies and in­di­vidu­als, and provides au­thors with a rig­or­ous and pro­fes­sion­al ed­it­or­i­al pro­cess. The Pa­cific Journ­al of Math­em­at­ics is in­cor­por­ated as a 501(c)(3) Cali­for­nia non­profit.

Sub­scribe to Open: Be­gin­ning with 2023, PJM is ad­opt­ing the Sub­scribe to Open mod­el: each year, if enough sub­scribers con­tin­ue to sup­port the journ­al, that year’s art­icles will be pub­lished open ac­cess — free to read by every­one and with no au­thor charges. The Sub­scribe to Open mod­el is fur­ther ex­plained here. We’re ex­cited to have found an equit­able open-ac­cess mod­el that makes sense for math­em­at­ics.

Up­date: Thanks to our sub­scribers, all 2026 art­icles in PJM will be pub­lished open ac­cess.
