View source for Global classical solutions of the relativistic Vlasov–Maxwell system

'''Global classical solutions of the relativistic Vlasov–Maxwell system''' concerns the large-data Cauchy problem for the system that describes a collisionless plasma whose particles move under their self-consistent electromagnetic field: whether smooth initial data in three space and three momentum dimensions always lead to a smooth solution for all time. A manuscript dated 23 September 2026 in OpenAI's public mathematics collection ([https://github.com/openai/math github.com/openai/math]), listed as its result 362, claims a unique global classical solution for the one-species system, with no smallness or symmetry assumption, and the collection includes a Lean formalization of this statement. This page summarizes the published claim and lists publicly available follow-up work. Statements are the respective authors' claims; the publication of a paper, code or a formal proof is not presented here as independent verification.

== Background ==
* As recounted in the introduction of the manuscript:
** Wollman established local existence and uniqueness of classical solutions. DiPerna and Lions developed global weak solutions for large data, and Rein gave a direct formulation for the relativistic one-species system; these weak solutions do not give the regularity and uniqueness of a classical theory.
** Glassey and Strauss identified bounded momentum support as a continuation condition for classical solutions and proved global existence for initially dilute plasmas. Glassey and Schaeffer proved global classical existence in dimensional reductions and for the spherically symmetric electrostatic reduction, and Rein proved persistence under small perturbations of suitable global solutions.
** Later proofs and refinements of the continuation criterion are due to Klainerman and Staffilani, Bouchut, Golse and Pallard, Luk and Strain, Pallard, and Sospedra-Alfonso and Illner. Small-data and small-particle results are due to Schaeffer, Bigorgne, X. Wang, and Wei and Yang; Bigorgne also constructed particular large global solutions from prescribed asymptotic data.
** X. Wang's two papers of July 2026 establish global existence for large cylindrically symmetric data in a different data class; the manuscript states that the two data classes should not be identified.

== The original result ==
* '''Claim.''' Theorem 1.1 of ''Global classical solutions of the three-dimensional relativistic Vlasov–Maxwell system'' states that every smooth admissible datum, namely a smooth nonnegative compactly supported particle density and fields with bounded derivatives of every order and finite energy satisfying both Gauss constraints, generates a unique global classical solution, smooth on every finite time interval, with compact phase-space support there and with the divergence constraints preserved. The manuscript notes that the momentum support bound may grow with the time interval and that a nonzero total charge is allowed.
* ''Method, as described:'' the central estimate bounds the signed change of a particle's momentum, with the norm taken after time integration; it implies that the time needed to double the largest momentum is bounded below by a sequence with divergent sum, so momentum support stays bounded on finite intervals and the Glassey–Strauss continuation criterion applies. The estimate uses the retarded representation of the fields, an identity writing the force along a source trajectory as a total derivative plus less singular terms, a bound on the number of direction changes, an improved occupation estimate and a selection argument, closed by a bootstrap.

* '''Formalization, as described by the repository.''' The [https://github.com/openai/math/blob/7ef5c0cc5ca4b0e072b7a050fca09ab24bc6fa3a/lean/docs/362.md scope note] states that the formalized result gives global existence and uniqueness for the three-dimensional one-species system for the stated data, with the solution smooth on every finite time interval, compact particle phase support there, uniqueness among classical solutions and no smallness, symmetry or neutrality assumption. The Comparator statement is <code>VlasovMaxwell.lean</code>.
