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.
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.
Classification of shift vectors in heterotic orbifold compactifications on Enriques surfaces with spectrum analysis and tachyon projection for non-supersymmetric interpretations.
Non-supersymmetric heterotic string compactifications on AdS4 x S3 x S3 with two fluxes develop tachyonic instabilities when fluxes are close in magnitude and show inverse scale separation when far apart, but brane nucleation always provides a decay channel that drives the fluxes together.
String theory imposes constraints on dark energy but permits various construction attempts for de Sitter vacua and single-field exponential quintessence models despite obstructions.
