--- _id: '66303' abstract: - lang: eng text: We propose an elementary tropical analogue of a reductive group that combines the datum of a Weyl group and the tropicalization of a fixed maximal torus. For the classical groups, as well as $G_2$, these tropical reductive groups admit descriptions as tropical matrix groups that resemble their classical counterparts. Employing this perspective, we introduce tropical principal bundles on metric graphs and study their explicit presentations as pushforwards of line bundles along covers with symmetries and extra data. Our main result identifies the essential skeleton of the moduli space of semistable principal bundles on a Tate curve with its tropical analogue. author: - first_name: Andreas full_name: Gross, Andreas last_name: Gross - first_name: Arne full_name: Kuhrs, Arne last_name: Kuhrs - first_name: Martin full_name: Ulirsch, Martin id: '114697' last_name: Ulirsch - first_name: Dmitry full_name: Zakharov, Dmitry last_name: Zakharov citation: ama: Gross A, Kuhrs A, Ulirsch M, Zakharov D.

We find a significant shift in bond market activity, evidenced by a 49% increase in the number of bond listings in the EEA30 countries relative to the UK market after Brexit. Country-level analyses reveal a staggered effect on market activity, with predominantly international issuers adjusting their bond listings between the initially scheduled Brexit date and the final withdrawal date. At the issuer level, our findings indicate that the relative attractiveness of the EEA30 market has increased post-Brexit. Overall, these results suggest that the European capital market has successfully adapted to the loss of its largest financial center and exhibits a rising corporate bond market activity. author: - first_name: Benedikt full_name: Franke, Benedikt last_name: Franke - first_name: Urska full_name: Kosi, Urska last_name: Kosi - first_name: Pia full_name: Stoczek, Pia last_name: Stoczek citation: ama: Franke B, Kosi U, Stoczek P.

Assuming a conjecture of Kantor our list of examples becomes a classification for chamber-regular C̃₂-lattices on locally-finite C̃₂-buildings. The links of special vertices in the buildings we construct, are all isomorphic to (the incidence graph of) the unique generalized quadrangle Q of order (3,5). In particular our constructions involve chamber-regular actions on Q. These actions on Q are the first (and if Kantor's conjecture holds the only) chamber-regular actions on a finite generalized quadrangle and therefore interesting in their own right. Moreover Q is not Moufang and therefore none of our examples is a Bruhat-Tits building and all our lattices are exotic building lattices. author: - first_name: Franziska full_name: Stamer, Franziska id: '121813' last_name: Stamer - first_name: 'Thomas ' full_name: 'Titz Mite, Thomas ' last_name: Titz Mite citation: ama: Stamer F, Titz Mite T.

This requires organizations to publicly display a work environment that fits the particular preferences of this target group. Drawing on lifespan theories, we examine how the link between employee preferences and employees’ likelihood of recommending their employer to others varies by age. To address the lack of integration between the literatures on workforce aging and employer branding, we take an empirical approach analyzing 292,429 numeric and unedited text-based employee reviews from an employer rating platform. Our findings reveal that relationship-building, fair and appreciative supervisor behavior, positive interactions with older colleagues, and location-flexible, efficient working conditions play pivotal roles in shaping older employees’ likelihood of recommending their employer. Although these age-related interaction effects are significant, they remain small, suggesting broadly compatible preferences between older and younger employees. We also demonstrate that these findings are robust across gender and different income groups. Finally, we provide tangible recommendations for the incorporation of lifespan theories in the employer branding context and highlight the value of using platform data for future research. author: - first_name: Ann Sophie full_name: Lauterbach, Ann Sophie last_name: Lauterbach - first_name: Katharina full_name: Radermacher, Katharina id: '47691' last_name: Radermacher citation: ama: 'Lauterbach AS, Radermacher K.

For initial data $u_{0}$ compactly supported or in a weighted $L^{1}(G/K)$ space with a weight depending on $p\\in [1, \\infty ]$, we introduce a mass function $M_{p}(u_{0})(\\cdot )$, and prove that if $h_{t}$ is the heat kernel on $G/K$, then $$ \\begin{align*} &\\|h_t\\|_p^{-1}\\,\\|u_0\\ast h_t \\, - \\,M_p(u_0)(\\cdot)\\,h_t\\|_p \\rightarrow 0 \\quad \\textrm{as} \\quad t\\rightarrow \\infty.\\end{align*} $$ Interestingly, the $L^{p}$ heat concentration leads to completely different expressions of the mass function for $1\\leq p &lt;2$ and $2\\leq p\\leq \\infty $. If we further assume that the initial data are bi-$K$-invariant, then our mass function boils down to the constant $\\int _{G/K}u_{0}$ in the case $p=1$, and more generally to $\\mathcal{H}{u_{0}}(i\\rho (2/p-1))$ if $1\\leq p&lt;2$, and to $\\mathcal{H}{u_{0}}(0)$ if $2\\leq p \\leq \\infty $. Thus, we improve upon results by Vázquez, Anker et al., and Naik et al., clarifying the nature of the problem." article_number: rnaf074 author: - first_name: Efthymia full_name: Papageorgiou, Efthymia id: '100325' last_name: Papageorgiou citation: ama: Papageorgiou E.

Such a model is essentially specified by a choice of a complex torus E and a symmetric positively definite matrix K of size g with non-negative integral coefficients, satisfying some further constraints. The space of the corresponding wave functions turns out to be \r\n \r\n $$\\delta $$\r\n \r\n \ δ\r\n \r\n \r\n \ -dimensional, where \r\n \ \r\n $$\\delta $$\r\n \r\n \ δ\r\n \r\n \r\n \ is the determinant of K.

A rigorous construction of this “magnetic bundle” involves the technique of Fourier–Mukai transforms on abelian varieties. The constructed bundle turns out to be simple and semi-homogeneous and it can be equipped with two different (and natural) hermitian metrics: the one coming from the center-of-mass dynamics and the one coming from the Hilbert space of the underlying many-body system. We prove that the canonical Bott–Chern connection of the first hermitian metric is always projectively flat and give sufficient conditions for this property for the second hermitian metric." article_number: '97' author: - first_name: Igor full_name: Burban, Igor id: '72064' last_name: Burban - first_name: Semyon full_name: Klevtsov, Semyon last_name: Klevtsov citation: ama: Burban I, Klevtsov S.

In this paper, we elaborate ring theoretic properties of nodal orders. In particular, we prove that they are closed under taking crossed products with finite groups.

The goal of this paper is to give an explicit computation of the curvature of the magnetic vector bundle of the multi-layer model of the fractional quantum Hall effect on a torus. We also obtain concrete formulae for the norms of the corresponding wave functions arising in such models.
