ive been defining the geometric transformation ive been studying in terms of the oriented blowup but it is much more geometrically native to the unoriented one, i think

cobordism as the space between: two manifolds are cobordant when a higher-dimensional manifold has their disjoint union as boundary. the cobordism group Ω_n classifies these equivalence classes.

Yes provided we're speaking of 1. linear transformations acting on a 2. (real or complex) vector space 3. equipped with an inner product. (2 and 3 could be combined into "real/complex inner product space" since "length" and "angle" are part of the context).
IIRC, angle/length here are unoriented :)

A “plane unit distance graph” (or abusively, just “unit distance graph”) is just a finite set P of points in the plane, which we turn into a(n unoriented) graph by declaring p,q∈P to be connected by an edge iff the distance between them is (exactly) 1. •2/16

There is some presumed conflict, but it is not merely ill-defined, it is UNDEFINED. This leaves the opening passages feeling vague and unoriented.

I'm actually not convinced of that either, but it also was on reflection not that relevant to the question of whether EM can be defined on an unoriented manifold. If it couldn't, we could still imagine that it manifests in some kind of domain wall that's just far away from us

physics "depends on" orientation. why should J go to -J? if we believe the world unoriented:
▪︎ Is it good enough to have available both +/-J, so that we can choose either [spurious] orientation and still go on to model any happenings? or
▪︎ Should we find out how to avoid orientations at any step
▪︎ Is it good enough to have available both +/-J, so that we can choose either [spurious] orientation and still go on to model any happenings? or
▪︎ Should we find out how to avoid orientations at any step

Erdős-Pósa property of $A$-paths in unoriented group-labelled graphs
We characterize the obstructions to the Erdős-Pósa property of $A$-paths in unoriented group-labelled graphs. As a result, we prove that for every finite abelian group $Γ$ and for every subset $Λ$ of ...

Orientable 2-Dimensional Cobordisms Are Classified By TQFTs, Enabling Advances In Khovanov Homology
Researchers have established a new mathematical framework that classifies two-dimensional topological field theories for surfaces with a defined orientation, bridging the gap between fully oriented and unoriented theories commonly used in modelling complex three-dimensional spaces.
