## Four P0 research tasks

[OP-MAT-001 stable electron solution](/en/open-problems/matter/electron-solution) · [OP-QM-004 Born statistics](/en/open-problems/quantum/born-statistics) · [OP-003 unified master equation](/open-problems/master-equation) · [OP-EXP-001 complete experimental discriminator](/en/open-problems/experiments/quantitative-discriminator)

P0 marks critical closure, P1 high priority and P2 normal work. READY only means the stated task can begin. NEEDS THEORY, NEEDS DATA and NEEDS EXPERIMENT identify the immediate prerequisite, not completion of everything else. Historical aliases are excluded from active-task counts by default; IDs and URLs remain valid.

## Find a task for your expertise

Combine priority, readiness and expertise filters, and search identifiers, current progress or deliverables. Filters are stored in the page address so you can share a link with collaborators. Each task shows its current state and reviewable deliverable; consult the original task for its conditions and sources.

<ProblemExplorer />

## Contribute a reviewable result

Read the task's known conditions, missing result, excluded routes and deliverables first. Contributions can be proofs, counterexamples, code, curated inputs or documented failures. Experimental sequencing is listed in the [priority workbenches](/en/tests/priority-experiments). A task's Researcher link carries its identifier, source page and knowledge snapshot so you can retrieve supporting material and export a research record. Model-answer availability follows the current deployment state shown in Researcher; new drafts do not automatically become canonical theory or public submissions.
