Question

Hello,
I would like to learn about how the constraints on 'hanging nodes' are handled in mesh adaptation. Where can I find relevant materials on this?

hello

You ll need to go in libMesh for this
It will be documented in the code
https://mooseframework.inl.gov/docs/doxygen/libmesh/index.html
not really any theory documentation on this implementation detail
