For atomic Hamiltonians with Kato potentials one can strengthen the result to obtain two-sided estimates for the sum of the negative eigenvalues. Instead of being in terms of the potential itself, as in the usual Lieb-Thirring result, the bounds are in terms of the landscape function, also known as the torsion function, which is a solution of $(-\\Delta + V +M)u_M =1$ in $\\mathbb{R}^d$; here $M\\in\\mathbb{R}$ is chosen so that the operator is positive.

Let g be a Lie algebra with an invariant, non-degenerate bilinear form &#10216; , &#10217;. Let R be a classical Rmatrix of g, this gives a modified Lie algebra gR. Consider the Kirillov-Kostant Poisson structures on the g&#8727; and g&#8727;R and denote Poisson brackets on g&#8727; and g&#8727;R by { , } and { , }R, respectively. Then all functions in the Poisson center with respect to { , } are commute with respect to { , }R. In this talk, we define the classical R-matrix for the vertex Lie algebras. We will see that a sufficient condition for an operator on a vertex Lie algebra to be a classical R-matrix is the modified Yang-Baxter equation (mYBE) of vertex Lie algebra which is an analog of the mYBE of Lie algebra. By using this R-matrix of vertex Lie algebra, we give a new scheme of integrability.</div><div class="event_time">15:30 &bull; Université de Genève, Conseil Général 7-9, Room 1-07</div>        </div>      </div>    </div>    <div class="day">      <div class="day_title">        Wednesday, June 5      </div>      <div class="day_content">        <div class="day_content_item normal"><div class="event_location uni_la"><a class="external" href="https://www.epfl.ch">EPF Lausanne</a></div><div class="event_type"><a class="external" href="https://www.unil.ch/dsa/en/home/menuinst/seminaires--evenements/research-seminars.html">Talks in Actuarial Mathematics </a></div><br /><div class="event_speaker"> Katrien Antonio (KU Leuven, Belgium)</div><div class="event_speaker"> Torsten Kleinow (University of Amsterdam)</div><div class="event_speaker"> Michel Vellekoop (University of Amsterdam)</div><div class="event_speaker"> Jens Robben (KU Leuven)</div><div class="event_title">Ecole d\'été <span class="abstract-button do_not_print">abstract</span></div><div class="abstract-text" style="display: none"><strong>Abstract:</strong><br />HEC welcomes actuaries from around the worldThe 35th International Summer School of the Swiss Association of Actuaries (ASA) will again be held on the campus of the University of Lausanne.

My talk will travel across diverse problem domains including randomized linear algebra, graph neural networks, protein family and structure discovery from metagenomic data, and tensor computations.

The existence problem, initially posed by Morawetz in 1985, has remained open since then. In this work, we establish the first complete existence theorem for the Morawetz problem by developing a new entropy analysis, coupled with a vanishing viscosity method and compensated compactness ideas. The main challenge arises when the flow approaches cavitation, leading to a loss of strict hyperbolicity of the system and a singularity of the entropy equation.

In this talk, we present a time-varying degree-corrected stochastic block model to fit a dynamic network which allows evolving heterogeneity in the degrees of nodes within a community over time. Considering the influence of the varying time window on the aggregation of network information from different time points, in the parameter estimation, we propose a smoothing-based method to recover time-varying degree parameters and communities.In particular we provide rates of consistency of our smoothed estimators for degree parameters and communities using a time-localised profile-likelihood approach. We illustrate our method by some comparative simulation studies and an application to a real data set.This is joint work with Mengxue Li and Eugen Pircalabelu (UCLouvain).</div><div class="event_time">15:15 &bull; EPF Lausanne, CM 1 517</div>        </div>      </div>    </div>  </div>  <div id="sms_footer">    address: Alessandra Naldi Windler, Departement Mathematik, HG G 51.4, ETH Zurich, Raemistrasse 101, CH-8092 Zurich<br />    email: <a href="mailto:bulletin@math.ch">bulletin@math.ch</a> | phone: +41 44 632 3684 | url: <a href="https://math.ch">https://math.ch</a>    <br /><br /><img src="//www2.math.ethz.ch/smsjs/sms_logo.gif" width="150" alt="SMS/SMG Logo" title="SMS/SMG Logo" />  </div></div>';
