When to sell an asset amid anxiety about drawdowns
(20200612)© 2020 The Authors. Mathematical Finance published by Wiley Periodicals LLC We consider riskaverse investors with different levels of anxiety about asset price drawdowns. The latter is defined as the distance of the current ... 
The evolution of knowledge within and across fields in modern physics
The exchange of knowledge across different areas and disciplines plays a key role in the process of knowledge creation, and can stimulate innovation and the emergence of new fields. We develop here a quantitative framework ... 
Diffusion Limits in the Online Subsequence Selection Problems
(Schloss Dagstuhl  LeibnizZentrum für Informatik, 20200610) 
Renormalization group theory of percolation on pseudofractal simplicial and cell complexes
Simplicial complexes are gaining increasing scientific attention as they are generalized network structures that can represent the manybody interactions existing in complex systems raging from the brain to highorder ... 
Algorithmic complexity of multiplex networks
(American Physical Society, 20200626)Multilayer networks preserve full information about the different interactions among the constituents of a complex system, and have recently proven quite useful in modelling transportation networks, social circles, and the ... 
Euler semigroup, HardySobolev and GagliardoNirenberg type inequalities on homogeneous groups
(Springer Verlag, 20200610)In this paper we describe the Euler semigroup $\{e^{t\mathbb{E}^{*}\mathbb{E}}\}_{t>0}$ on homogeneous Lie groups, which allows us to obtain various types of the HardySobolev and GagliardoNirenberg type inequalities for ... 
Distinguished correlation properties of Chebyshev dynamical systems and their generalizations

A spatial joint analysis of metal constituents of ambient particulate matter and mortality in England
(Lippincott, Williams & Wilkins, 2020)Background Few studies have investigated associations between metal components of particulate matter on mortality due to wellknown issues of multicollinearity. Here, we analyze these exposures jointly to evaluate their ... 
Zeroone Schubert polynomials
(Springer (part of Springer Nature), 2020)We prove that if σ∈Sm is a pattern of w∈Sn, then we can express the Schubert polynomial 𝔖w as a monomial times 𝔖σ (in reindexed variables) plus a polynomial with nonnegative coefficients. This implies that the set of ... 
Harmonic and Anharmonic Oscillators on the Heisenberg Group
Although there is no canonical version of the harmonic oscillator on the Heisenberg group $\mathbf{H}_n$ so far, we make a strong case for a particular choice of operator by using the representation theory of the DyninFolland ... 
Hyperbolic systems with nondiagonalisable principal part and variable multiplicities, II: microlocal analysis
In this paper we continue the study of nondiagonalisable hyperbolic systems with variable multiplicity started by the authors in \cite{Garetto2018}. In the case of space dependent coefficients, we prove a representation ...
