Newspace 10.2.a: S2new(ฮ“0(10))S_{2}^{\mathrm{new}}(\Gamma_0(10))

Newforms

There are no newforms: S2new(ฮ“0(10))=0S_{2}^{\mathrm{new}}(\Gamma_0(10)) = 0.

Dimensions

Newforms S2new(ฮ“0(10))S_{2}^{\mathrm{new}}(\Gamma_0(10))0
Old forms0
Cusp forms S2(ฮ“0(10))S_{2}(\Gamma_0(10))0
Eisenstein series E2(ฮ“0(10))E_{2}(\Gamma_0(10))3
Modular forms M2(ฮ“0(10))M_{2}(\Gamma_0(10))3

Decomposition of the old subspace

The old subspace is 0.

Provenance

Stored in the atlas: computed by Sagebrush's modular symbols engine in 0 s (one thread) and proven: the dimensions are certified, and the characteristic polynomial of TT over Z\mathbb{Z} is reconstructed by CRT past a rigorous coefficient bound.

The engine's checks
    Open in the notebook ยท JSON ยท stored data
    Recompute it yourself

    In Sage mode at sagebrush.space (or npx sagebrush --sage):

    newform_orbits(10, 2)

    With the Rust engine (source), in engine/:

    cargo run --release -p sagebrush-web --example atlas -- 10:2 1000
