I have studied "enough" the theory of distributions , I would like to deepen some topic with applications. With some research I arrived at this book:

"Geometric Theory of Generalized Functions with Applications to General Relativity (Mathematics and Its Applications) (Volume 537)" by Michael Grosser, Michael Kunzinger, Michael Oberguggenberger and Roland Steinbauer.

You can find the index (and some pages) on google books or amazon. Does anyone know this theory? which prerequisites are more fundamental to study from this book? thanks for every answer.
