Other manuscripts:

Ph.D. Thesis, Techinon - Israel Institute of Technology, 2011. (Hebrew abstract)

This note closes a gap in the proof of Proposition 1.10 of the paper: Patching and admissibility over two dimensional complete local domains. It appears in Algebra and Number theory 5-2 (2011), 287-288.

Admissibility and realizability over number fields - this manuscript is almost fully covered by my thesis.
