**Quantum Gravity Problem:**

**Below is a compilation of George Karatheodoris’ scanned notebooks. His untimely death resulted in the bulk of his work on gauge gravity to remain unpublished. They are presented here in reverse chronological order. Volumes for previous years are still in the process of being uploaded. A complete volume list (indicating topics covered in each notebook) is found here**

##### **Why Scan the Notebooks?**

A note from the author explains: * “…I have to write extremely terse papers in the code (TeX code) for the articles. I will cite pages from notebooks in which details are carried out. I just don’t have time to make the papers pedagogical as much as I might like to.” *** **(from notebook: February 2012-July 2012, p. 20.)

**Organization and Presentation**

The notebooks are scanned in their entirety as it’s impossible to know which the author intended to scan and reference for his articles. Each title block below begins with a the date, some topic(s) covered, followed by the notebook’s “Page Link” below it. The “Page Link” takes the reader to the notebook PDF. For efficiency in identification of content, some transcribed notations are provided with their corresponding page numbers.
