We study the Virasoro conformal block decomposition of the genus two partition function of a two-dimensional CFT by expanding around a ℤ3-invariant Riemann surface that is a three-fold cover of the Riemann sphere branched at four points, and explore ...

A Re‐Examination of Foundational Elements of Cosmology
ABSTRACT This paper undertakes a conceptual re‐examination of several foundational elements of cosmology through the lens of spacetime symmetries. A new derivation of the Friedmann–Lemaître–Robertson–Walker metric is obtained by a careful conceptual examination of rotations and translations on generic manifolds, followed by solving the rotational and ...

The super period matrix with Ramond punctures in the supergravity formulation
In a very recent preprint, Witten showed how to construct a g|r×g|r super period matrix for super Riemann surfaces of genus g with 2r Ramond punctures, which is symmetric in the Z2 graded sense.

Model Validation of M‐I Coupling in SWMF
Abstract The accurate modeling of field‐aligned currents (FAC) and electron precipitation is critical for understanding magnetosphere‐ionosphere coupling and improving space weather predictions. This study evaluates the performance of the SWMF in replicating observed FAC magnitudes and distributions, as well as electron precipitation during storms and ...

Kernel function and integral representations on Klein surfaces
Some representation theorems for the solutions of the Dirichlet problem and the Neumann problem on Klein surfaces are proved by using an analogue of the harmonic kernel function on symmetric Riemann surfaces.

Deformaciones isométricas infinitesimales de una clase de superficies pegadas
In this work the sufficient condition of rigidity of a stuck 4-dimensional surface in the Euclidean 6-dimensional space is demonstrated. This surface represents in himself, the product of Riemann of two surfaces, each one of which it is in the Euclidean ...

Abstract The Deepwater Horizon (DWH) oil spill in the NE Gulf of Mexico in 2010 was the largest accidental spill globally. During and after the spill, oil was incorporated into marine snow (marine‐oil‐snow or MOS) and sedimented to the seafloor, accounting for ∼21% of the oil released.

Teichmüller Theory of Bordered Surfaces
We propose the graph description of Teichmüller theory of surfaces with marked points on boundary components (bordered surfaces). Introducing new parameters, we formulate this theory in terms of hyperbolic geometry.

2-Rényi CCNR negativity of compact boson for multiple disjoint intervals
We investigate mixed-state bipartite entanglement between multiple disjoint intervals using the computable cross-norm criterion (CCNR). We consider entanglement between a single interval and the union of remaining disjoint intervals, and compute 2-Rényi ...
