Maslov $S^{1}$ Bundles and Maslov Data

Konstantinos Efstathiou, Bohuan Lin, Holger Waalkens

We define Maslov $S^{1}$ bundles over a symplectic manifold $(M, ω)$ . These are the determinant bundle $Γ_{J}$ of the unitary frame bundle defined by an almost complex structure compati…

Topological bias: How haloes trace structural patterns in the cosmic web

Raul Bermejo, Georg Wilding, Rien van de Weygaert +3

We trace the connectivity of the cosmic web as defined by haloes in the Planck-Millennium simulation using a persistence and Betti curve analysis. We normalise clustering up to the…
