Seminario di Tyler Helmuth (Bristol) a Roma Tre, 12-12-2019

SEMINARIO Probabilita' Tyler Helmuth (University of Bristol) Titolo: Random spanning forests and hyperbolic symmetry Giovedi' 12 Dicembre 2019 ORE 10:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract The arboreal gas is a probability measure that arises from conditioning the random subgraph given by Bernoulli(p) bond percolation to be a spanning forest, i.e., to contain no cycles. This conditioning makes sense on any finite graph G, and specializes to the uniform measure on spanning forests when p = 1/2. One is naturally lead to ask about the percolative properties of the arboreal gas, and this turns out to be a surprisingly rich question. I will discuss some results and conjectures about the arboreal gas, most of which are based on important relations between the arboreal gas and spin systems with hyperbolic symmetry. Based on joint work in progress with Roland Bauerschmidt, Nick Crawford, and Andrew Swan.

Economists For Future (fwd)
by Tiziano Vargiolu 02 Dec '19

02 Dec '19

Per completezza: c'e' una cosa molto importante che non viene detta sotto, ma nella procedura di firma si', ed e' questa: IMPORTANT: This open letter is open to everyone to sign, not just economists! Cordiali saluti a tutti ---------- Forwarded message ---------- Date: Mon, 02 Dec 2019 13:16:12 +0000 From: Luisa Jentsch <noreply(a)econ4future.org> Reply-To: info(a)econ4future.org To: Tiziano <vargiolu(a)math.unipd.it> Subject: Economists For Future Dear Tiziano, I write to introduce you to Economists for Future?s open letter that is calling on the economics community to raise its game and devise a more impactful contribution to tackling climate change. Economists for Future is an international student-led organisation with the aim to put pressure on the economics community to treat climate change like the emergency it is. While many economists have shown great academic leadership on this issue, the overall contribution from the community has not been commensurate with the magnitude of the problem. The shortage of climate change related articles in top journals is one such demonstration. For example, the most-cited journal in our discipline has never published an article on climate change [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/YJmX2li…] As the next generation of economists, as young people who will live through the most severe climate effects and as individuals with a deep belief in the power of good economics to make the world a better place, we feel an acute pressure to ?do more? that we are hoping you will share. We think economists have both a responsibility and an enormous opportunity to have an even greater contribution to help tackle this emergency. The open letter (attempts to) make the case for economists seizing this opportunity to provide the intellectual framework that enables a rapid decarbonisation that is coupled with a great leap in human progress. We would like to invite you to support this initiative by signing the letter, which you can do by filling out the form on our website. [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/K8_4G0o…] And, if you agree with it, we would kindly ask you to share your support among your social and academic networks. If you have any questions about our initiative or the letter, we would love to hear from you ? at the end of the day, we are curious students that desire more from the discipline we want to dedicate our lives to. Kind Regards, Luisa Jentsch Economists For Future Website: econ4future.org [econ4future.org] Facebook [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/CY-m9M0…] Instagram [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/qHhHAzS…] Twitter [https://lists.econ4future.org/links/iJ9AW4JXP/PfQP6QyMO/aMbvBGRdzdg/zMI73YS…]

Seminario Prof. Claudio Macci

Il Prof. Claudio MACCI dell'Università di Roma Tor Vergata mercoledì 4 dicembre 2019 alle ore 16 nell'Aula E al III livello del Dipartimento di Matematica e Applicazioni dell'Università degli Studi di Napoli Federico II terrà un seminario dal titolo: Large deviations for risk measures in finite mixture models ABSTRACT Due to their heterogeneity, insurance risks can be properly described as a mixture of different fixed models, where the weights assigned to each model may be estimated empirically from a sample of available data. If a risk measure is evaluated on the estimated mixture instead of the (unknown) true one, then it is important to investigate the committed error. In this paper we study the asymptotic behaviour of estimated risk measures, as the data sample size tends to infinity, in the fashion of large deviations. We obtain large deviation results by applying the contraction principle, and the rate functions are given by a suitable variational formula; explicit expressions are available for mixtures of two models. Finally, our results are applied to the most common risk measures, namely the quantiles, the expected shortfall and the shortfall risk measure. Joint work with Valeria Bignozzi and Lea Petrella.

Avviso di Seminario, università di Trento Stochastic homogenization in amorphous media and applications to interacting particle systems and random resistor networks Giovedì 5 dicembre 2019 Luogo: Polo Ferrari 1, via Sommarive, 5 - Povo (TN) - Aula A221 Ore: 16:00 Relatore: Alessandra Faggionato (Università La Sapienza, Roma) Abstract: We consider random walks on marked simple point processes with symmetric jump rates and unbounded jump range. Examples are given by simple random walks on Delaunay triangulations or Mott variable range hopping in doped semiconductors. We present homogenization results for the associated Markov generators. As a first application, we obtain the hydrodynamic limit of the exclusion process given by multiple random walks as above, with hard–core interaction. As a second application, we derive a limit theorem for the effective conductivity of some classes of random resistor networks. This result together with a percolation-type analysis allows to derive the low temperature scaling behavior of conductivity in some classes of strongly disordered media.
