This entry is about the conjectured relation (duality) between M-theory at MO9-planes and heterotic string theory on these. For the relation of M-theory KK-compactified on a K3-surface and heterotic string theory on a 3-torus see instead at duality between M/F-theory and heterotic string theory.
general mechanisms
electric-magnetic duality, Montonen-Olive duality, geometric Langlands duality
string-fivebrane duality
string-QFT duality
QFT-QFT duality:
effective QFT incarnations of open/closed string duality,
relating (super-)gravity to (super-)Yang-Mills theory:
Seiberg duality (swapping NS5-branes)
There is an observation by Hořava–Witten 95, Hořava–Witten 96 which suggests that M-theory on an Z/2-orbifold (actually a higher orientifold) of the form is “dual” to heterotic string theory on its boundary (fixed point) “M9-brane”. Therefore one also speaks of “heterotic M-theory” (Ovrut 02).
from Kashima 00
In the above the circle factor is taken to be the circle fiber over the 10d type IIA spacetime.
If instead one considers another of the spatial dimensions to be compactified on , then, after T-duality (F-theory) result is supposed to be type I string theory. In this case the intersection of the M2-brane with the M9-brane (the latter now wrapping the M-theory circle fiber) is called the E-string.
More in detail:
One considers the KK-compactification of M-theory on a Z/2-orbifold of a torus, hence of the Cartesian product of two circles
such that the reduction on the first factor corresponds to the duality between M-theory and type IIA string theory, hence so that subsequent T-duality along the second factor yields type IIB string theory (in its F-theory-incarnation). Now the diffeomorphism which exchanges the two circle factors and hence should be a symmetry of M-theory is interpreted as S-duality in type II string theory:

If one considers this situation additionally with a -orbifold quotient of the first circle factor, one obtains the duality between M-theory and heterotic string theory (Horava-Witten theory). If instead one performs it on the second circle factor, one obtains type I string theory.
Here in both cases the involution action is by reflection of the circle at a line through its center. Hence if we identify then the action is by multiplication by /1 on the real line.
In summary:
M-theory on
yields heterotic string theory
yields type I' string theory
Hence the S-duality that swaps the two circle factors corresponds to a duality between heterotic E and type I’ string theory. And T-dualizing turns this into a duality between type I and heterotic string theory.

Here each of the two copies of the heterotic gauge theory is a “hidden sector” with respect to the other.
The orbifold equivariance condition of the supergravity C-field is that discussed at orientifold (there for the B-field). Therefore it has to vanish at the two fixed fixed points of the -action. Thereby the quantization condition
on the supergravity C-field becomes the condition for the Green-Schwarz mechanism of the heterotic string theory on the “boundary” (the orbifold fixed points).
duality between M-theory and type I string theory
originally suggested in (Horava-Witten 95, section 3)
Further evidence is reviewed in APT 98
duality between heterotic and type I string theory
via S-duality in the F-theory-picture…
The supergravity C-field is supposed to vanish, and differentially vanish at the boundary in the HW model, meaning that also the local connection 3-form vanishes there. The argument is roughly as follows (similar for as in Falkowski, section 3.1).
in the Lagrangian of 11-dimensional supergravity is supposed to be well-defined on fields on the orbifold and hence is to be -invariant.
Let be the canonical vector field along the circle factor. Then the component of which is annihilated by the contraction is necessarily even, so the component is also even. It follows that also is even.
Moreover, the kinetic term
is to be invariant. With the above this now implies that the components of annihiliated by is odd, because so is the mixed component of the metric tensor.
This finally implies that the restriction of to the orbifold fixed points has to be closed.
