Orientifold limits of singular -theory vacua
James Fullwood, Dongxu Wang
We construct global orientifold limits of singular -theory vacua whose associated gauge groups are SO(3), SO(5), SO(6), , SU(4), and Spin(7). For each limit we show a unive…
On the Sen limit squared
James Fullwood, Dongxu Wang
We introduce a class of F-theory vacua which may be viewed as a specialization of the so-called fibration, and construct a weak coupling limit associated with such vacua whic…
Towards a simple characterization of the Chern-Schwartz-MacPherson class
James Fullwood, Dongxu Wang
For a large class of possibly singular complete intersections we prove a formula for their Chern-Schwartz-MacPherson classes in terms of a single blowup along a scheme supported on…
On a relative form of Verdier Specialization
James Fullwood, Dongxu Wang
We prove a relative form of Verdier's specialization formula, and apply it to derive a Chern class identity predicted by string dualities.
On CSM classes via Chern-Fulton classes of f-schemes
James Fullwood, Dongxu Wang
The Chern-Fulton class is a generalization of Chern class to the realm of arbitrary embeddable schemes. While Chern-Fulton classes are sensitive to non-reduced scheme structure, th…
