Discretizing bifurcation Diagrams Near codimension Two Singularities
We consider parameter-dependent, continuous-time dynamical systems under discretizations. It is shown that fold-Hopf singularities are O(h)-shifted and turned into fold-Neimark-Sacker points by one-step methods of order p. Then we analyze the effect of discretizations methods on the local bifurcation diagram near BogdanovTakens and fold-Hopf singularities. In particular we prove that the discre...
متن کاملCodimension-Three Bundle Singularities in F-Theory
We study new nonperturbative phenomena in N = 1 heterotic string vacua corresponding to pointlike bundle singularities in codimension three. These degenerations result in new four-dimensional infrared physics characterized by light solitonic states whose origin is explained in the dual F-theory model. We also show that such phenomena appear generically in E7 → E6 Higgsing and describe in detail...
متن کاملSimple Cohen-Macaulay Codimension 2 Singularities
In this article, we provide a complete list of simple isolated CohenMacaulay codimension 2 singularities together with a list of adjacencies which is complete in the case of fat point and space curve singularities.
متن کاملPulling Back to Move Forward
Animal cells can change shape and move by using actin polymerization to drive plasma membrane protrusion. Giannone and coworkers (this issue of Cell) describe how cells periodically pull back on these protrusions in order to sense and respond to the rigidity of their environment.
