I am Stephan Wehner, a mathematician and software developer, live with my partner Tamara in Vancouver, Canada, and devote most of my free time to my two daughters Astrid and Isabella.

This blog is meant firstly, to consolidate my previous home page, which became quite scattered over the years. Then also, the WordPress blogging software makes it a lot easier to  maintain a website.  Some ordinary blog-articles may appear in the future, but probably not frequently or regularly.
