Hi everyone. I'm Víctor M. Vega Assistant Professor of Mathematics here at St. Ambrose.  Here you can find useful information about me and my research, the courses I teach, math links, cool sites and more. Look at some of the pictures in this site and you will find what is going on there. These are pictures from the work of E. M. Escher. Check out the book Impossible worlds by Bruno Ernst with all the graphic work of the extraordinary Escher. Enjoy !!!
