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.

abstract
Open-string theories may be related to suitable models of oriented closed strings. The resulting construction of ``open descendants'' is illustrated in a few simple cases that exhibit some of its key features.

Explicit worldsheet constructions of 9d junctions joining several 10d string theories via generalized RG flow interpolations and closed tachyon condensation, providing dynamical realizations of multi-theory cobordisms.
Global gauge groups match in the Blum–Dienes duality, but the Bergman–Gaberdiel duality needs an unexplained extra Z2 projection on type 0B orientifold branes.
Non-supersymmetric heterotic AdS4 × S³ × S³ solutions exhibit a coupled instability: comparable fluxes trigger perturbative tachyons, while brane nucleation drives unequal fluxes toward that tachyonic regime.
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 existing dualities.
Classifies shift vectors for heterotic orbifolds on Enriques surfaces, analyzes spectra, and interprets some models as non-supersymmetric 10D heterotic compactifications with tachyon projection.
Classifies singularity structures and asymptotics of cosmological solutions driven by exponential string potentials and curvatures k, k' in maximally symmetric spaces, emphasizing flat slices.
String theory imposes constraints on dark energy but permits various construction attempts for de Sitter vacua and single-field exponential quintessence models despite obstructions.
