On the growth of the Kronecker coefficients: accompanying appendices

This text is an appendix to our work "On the growth of Kronecker coefficients" [1]. Here, we provide some complementary theorems, re- marks, and calculations that for the sake of space are not going to appear into the final version of our paper. We follow the same terminology and notation. External references to numbered equations, theorems, etc. are pointers to [1]. This file is not meant to be read independently of the main text.
