Dear visitor, I honestly don't (and, even more honestly, I doubt I ever will) understand that whole copyright ball-game when it comes to the publications presenting research materials. I tend to highly agree with Jeff Erickson (despite the modest claim that it is outdated, the page still has some neat links to the Computational Geometry sites, nice!!!) in his view on the copyright. Most of my publications are accessible through the DBLP, an excellent source of bibliographic materials (albeit, sometimes slightly-not 100% complete-in-time), for which credit must be given to Michael Ley. You can get the DBLP-available version of some of my publications if you look at my research page describing the crux of some of the topics I've worked on. In case you have any problems obtaining an electronic version of some of my publications, please drop me a line and I will respond promptly.
