My research interest are as follows, where the most recent topics are listed first.
I am currently the Chair of our CAGS at GMU mathematics department, as I have been for many years.
Those who want to give a talk, should email me, Geir, the title and a short abstract.

My graph theory book that my coauthor Ray Greenlaw and I wrote together, was published by in Septemeber 2007. I maintain an ERRATA sheet for various typos and mistakes that we the authors find and that also keep trickling in from users of this book from all around the world! Further comments and related references are always welcomed!  Sincere thanks to Prof. Robert W. Robinson at The University of Georgia (UGA) and the students of his Math(CSCI)  4690/6690 graph theory class of Spring 2009, who used this textbook and found numerous typos and other small (yet embarrassing!) mistakes. Complete solutions to a selected number of exercises are available from the publisher, Pearson Prentice Hall. Instructors should contact Executive Editor Jeff Weidenaar (Email: jeff.weidenaar THEATSIGN pearson PERIOD com, Phone 7819290824) for the solutions.  Needless to say, comments on typos and other SNAFUs in these solutions are always welcomed! 
During this strange COVID19 pandemic Spring Semester of 2020, I am teaching the following courses:
