Coherent tangent bundles and Gauss-Bonnet formulas for wave fronts
Kentaro Saji, Masaaki Umehara, Kotaro Yamada
We give a definition of `coherent tangent bundles', which is an intrinsic formulation of wave fronts. In our application of coherent tangent bundles for wave fronts, the first fund…

The duality between singular points and inflection points on wave fronts
Kentaro Saji, Masaaki Umehara, Kotaro Yamada
In the previous paper (arXiv:0804.0701), the authors gave criteria for A_{k+1}-type singularities on wave fronts. Using them, we show in this paper that there is a duality between…
