Based on https://arxiv.org/abs/2106.01373. We study a model for
explaining the apparent deviation of the muon anomalous magnetic
moment, (g-2), from the Standard Model expectation. There are no
new scalars and hence no new hierarchy puzzles beyond...
There is notion of a smooth categorical compactification of
dg/A-infinity categories: for example, a smooth compactification of
algebraic varieties induces a smooth categorical compactification
of the associated bounded dg categories of coherent...
While by a result of McDuff the space of symplectic embeddings
of a closed 4-ball into an open 4-ball is connected, the situation
for embeddings of cubes C4=D2×D2 is very different. For
instance, for the open ball B4 of capacity 1, there exists
Eliashberg and Thurston showed that taut foliations on
3-manifolds can be approximated by tight contact structures. I will
explain a new approach to this theorem which allows one to control
the resulting Reeb flow and hence produce many hypertight...
Siegel has recently defined ‘higher’ symplectic
capacities using rational SFT that obstruct symplectic embeddings
and behave well with respect to stabilisation. I will report on
joint work with Julian Chaidez that relates these capacities to
I will describe my recent work, joint with Shaoyun Bai, which
studies a class of bifurcations of moduli spaces of embedded
pseudo-holomorphic curves in symplectic Calabi-Yau 3-folds and
their associated obstruction bundles. As an application, we
Discussions of the widespread appeal of the cult of Isis in
antiquity often omit any mention of the Nubian priests who served
the rulers of the Kingdom of Meroe (located south of Egypt in the
Sudan) and the royal donations of gold that they...
