Title:
"Flat tori and Origami"

Abstract:
 We consider origami embeddings of flat tori. For piecewise-linearly embedded surfaces, one can define lengths of piecewise smooth paths, and hence one can consider this question. Intuitively, the geodesics are lines on the surface locally developed to the plane. My motivation to look at this question was that an explanation of the Nash-Kuiper embedding theorem for piecewise smooth embedding cases looked much easier. In particular, since flat manifolds are easily (semi-)locally origami embedded, it looked possible to give explicit global origami embeddings. It has already been known that flat tori can be origami embedded, however, it is interesting for me to show them explicitly.

Title:
"Knot theoretical analysis of site-specific recombination of DNA"

Abstract:
 We explain the application of knot theory to the study of site-specific recombination of DNA. We characterize the unlinking pathway of a site-specific recombination system and discuss related topics.
