Dynamical Horizons and Black Hole Soft Hair
Albert Huber
In the present work, quasilocal Brown-York charges are derived that coincide in the large sphere limit with the conserved supertranslation hair and superrotation charges introduced…

General Shells and Generalized Functions
Albert Huber
In this work, standard methods of the mixed thin-shell foramlism are refined using the framework of Colombeau's theory of generalized functions. To this end, systematic use is made…
