**About**

My name is Roman Kogan. I am a math PhD student at Texas A&M University. My undergraduate degree was from SUNY Stony Brook.

**Research and other work**

Here is some of my work:

- Joint paper with B.Bischof, D.N.Yetter:
*On a Basis for the Framed Link Vector Space Spanned by Chord Diagrams*, accepted for publication in Journal of Knot Theory and Ramifications.

See Preprint at ArXiv. - Chord Diagrams, a Java/Mathematica software for that paper;
- NvTrees,
*n*-dimensional Thompson groups calculator (Java Applet and Standalone); - Evolutes, a program that draws involutes, evolutes an osculating circles for a given curve.
- If you are into computational geometry, you might like the Delaunay triangulation applet, which illustrates the algorithm of computing it by a lift to paraboloid.
- If you need to visualize the Newton polyhedron of a polynomial and count lattice points inside it, Newton Polytope applet does precisely that.

**Other**

Listen to my electronic
music, see my
photographs, read my survey of history of elctronic music
(get a print version: [PDF] with less typos). See a cool Processing-JS demo, and Cross-eye pseudo-3D demo.
Try the arcball interface implemented in Javascript (again, with Processing/JS).
If you have a webcam, play with the Webcam Scanner Camera.
