It is conjectured that the two closed bosonic string theories, Type 0A and Type 0B, correspond to certain supersymmetry breaking orbifold compactifications of M-theory. Various implications of this conjecture are discussed, in particular the behaviour of the tachyon at strong coupling and the existence of non-perturbative fermionic states in Type 0A. The latter are shown to correspond to bound states of Type 0A D-particles, thus providing further evidence for the conjecture. We also give a comprehensive description of the various Type 0 closed and open string theories.

  1. Recursive-algebraic solution of the closed string tachyon vacuum equation

    hep-th 2026-03 unverdicted novelty 7.0

    A seam-graded expansion turns the closed string tachyon vacuum equation algebraic at every order, reducing it to matrix inversions in the zero-momentum scalar sector.

  2. Recursive-algebraic solution of the closed string tachyon vacuum equation

    hep-th 2026-03 unverdicted novelty 7.0

    Presents a seam-graded recursive algebraic method that converts the closed string tachyon vacuum equation into a sequence of matrix inversions in the zero-momentum Lorentz-scalar sector.

  3. Ho\v{r}ava-Witten theory on ${\mathbf{S}}^1\vee{\mathbf{S}}^1$ as type 0 orientifold

    hep-th 2026-03 unverdicted novelty 7.0

    Hořava-Witten theory on S¹∨S¹ is dual to a type 0B orientifold with SO(16)^4 gauge group, explaining gauge group doubling via the geometry's junction and revealing two variants from E8 wall orientations.

    hep-th 2026-05 unverdicted novelty 6.0

    Proposes a refinement of the Swampland Cobordism Conjecture for Ω1(BG) with duality bundle G, where diverging commutator width of G requires infinitely many duality defects to realize monodromies via gravitational solitons.

    A duality web is proposed in which Z2 quotients of M-theory on S1 vee S1 and F-theory on (S1 vee S1) x S1 map to 0A/0B orientifolds and non-supersymmetric E-type and D-type heterotic strings, providing evidence for ex...
