Corks and exotic ribbons in $$B^{4}$$
نویسندگان
چکیده
By using corks we construct diffeomorphic ribbon disks \(D\subset B^{4}\), which are not smoothly isotopic rel boundary to each other.

Corks, Buoyancy, and Wave-Particle Orbits
The motion of open ocean waves and associated water-particle orbits constitute a focused topic that occupies a lasting niche in our arsenal of simple, pedagogically compelling things to offer introductory students in the geosciences. The topic provides a vehicle for introducing the general subject of wave behavior, a universally important phenomenon in the geosciences; it challenges students to...
متن کاملNanocrystallization in Co67Cr7Fe4Si8B14 Amorphous Alloy Ribbons
The nanocrystallization of Co67Fe4Cr7Si8B14 amorphous ribbons which prepared by planar flow melt spinning process (PFMS) was investigated. Crystallization of the ribbons was studied by differential thermal analysis (DTA), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The DTA result of amorphous ribbon at heating rate of 10˚C/min showedoccurrence of phase transitions in two...
