On the problem of filling by a Poincaré-Einstein metric in dimension 4
Given a metric defined on a manifold of dimension three, we study the problem of finding a conformal filling by a Poincaré-Einstein metric on a manifold of dimension four. We establish a compactness result for classes of conformally compact Einstein $4$-manifolds under conformally invariant conditions. A key step in the proof is a result of rigidity for the hyperbolic metric on $\mathbb {B}^4$ or $ S^1 \times \mathbb{B}^3$. As an application, we also derive some existence results of conforma…

From finding a spanning subgraph $H$ to an $H$-factor

From finding a spanning subgraph $H$ to an $H$-factor
A typical Dirac-type problem in extremal graph theory is to determine the minimum degree threshold for a graph $G$ to have a spanning subgraph $H$, e.g. the Dirac theorem. A natural following up problem would be to seek an $H$-factor, which a spanning set of vertex-disjoint copies of $H$. In this short note, we present a method of obtaining an upper bound on the minimum degree threshold for an $H$-factor from one for finding a spanning copy of $H$. As an application, we proved that, for all $…

Electron-muon conversion in nuclei and rare decays induced by LFV dark photon
We study lepton flavor violation (LFV) effects occurring in the $e-μ$ conversion in nuclei and in the rare radiative decays $η(η') \to γμe$ of the $η$ and $η'$ mesons with a special impact of the sub-GeV mass vector mediator (dark photon). In the case of the lepton conversion we make estimates for running and future experiments operating with electron beams at fixed target. Obtained results are implemented in analysis of the LFV decays $η(η') \to γμe$. In particular, we derive the fo…

Stability and optical quality of liquid crystal films as high repetition rate plasma mirrors in staged laser-plasma accelerators
Staging multiple laser-plasma accelerators (LPAs), each driven by its own laser pulse, is a promising technique for reaching higher particle energies than achievable in a single LPA. However, introducing subsequent laser pulses for post-acceleration in staged LPA geometries presents a significant challenge for conventional optics. Due to the focused, high-intensity nature of the laser beam interacting with the electron beam, the fluence on the coupling mirror surpasses the damage threshold of a…

We have a five-alarm fire inside the #DepartmentOfJustice. I’ve been telling you about the dominoes falling over the last few months. Now it’s all coming to a head. We must stay alert, informed, and outspoken.
