The answer to the key question takes advantage of recent research activity documented in the five titles in the bibliography. The answer opens to challenging research perspectives. [1] B.N. and C.

•  feb24wed2016 Seminar02-24-2016, 17:00 Divergent series: from thomas bayes’s bewilderment to today’s resurgence via the rainbowSir Michael Berry SEMINAR ONDivergent series: from thomas bayes’s bewilderment to today’s resurgence via the rainbowSir Michael Berry, H H Wills Physics Laboratory, Bristol, UKWednesday, february 24 2016 at 17:00, Sala Consiglio, 7 piano, Dipartimento di Matematica, Via Bonardi 9, MilanoAbstractFollowing the discovery by Bayes in 1747 that Stirling’s series for the factorial is divergent, the study of asymptotic series has today reached the stage of enabling summation of the divergent tails of many series with an accuracy far beyond that of the smallest term. Several of these advances sprang from developments of Airy’s theory of waves near optical caustics such as the rainbow. Key understandings by Euler, Stokes, Dingle and Écalle unify the different series corresponding to different parameter domains, culminating in the concept of resurgence: quantifying the way in which the low orders of such series reappear in the high orders.

•  mar03thu2016 Seminar03-03-2016, 11:00 Large scale flow simulationsBarbara Wohlmuth SEMINAR ONLarge scale flow simulationsBarbara Wohlmuth , TU MünchenThursday, march 3 2016 at 11:00, Aula Seminari AbstractLarge scale flow problems play an important role in many multi-physics applications. In this talk, we consider different aspects such as the role of local mass conservation in a weak or strong setting and non-linear solution techniques in case of inequality constraints. Many natural pairings of conforming discrete spaces do not satisfy a uniform inf-sup condition and thus do have either to be stabilized or the velocity space has to be enriched. Quite often these standard techniques result in discrete velocities which do not yield strongly the divergence free condition. Here we propose easy to realize local a posteriori corrections which allow us to lift the $H^1$-conforming velocity onto a $H(\text{div})$-conforming mixed finite element, e.g. of Raviart–Thomas type. By doing so we achieve a significantly improved accuracy in case of coupled transport terms where, e.g., the velocity enters into the advective part of an energy equation. Secondly we consider an example from porous media flow and discuss the role of inequality constraints on the saturation. In contrast, to simple contact laws where a non-linear complementarity condition can be defined in terms of the max-function and affine terms, non-linear constitutive relations also enters. Thus the realizations of active set strategies are more involved. Nevertheless, robust numerical results can be obtained if combined with an adaptive time stepping scheme. contact: paola.antonietti@polimi.it Politecnico di Milano, Dipartimento di Matematica via Bonardi 9, 20133 Milano – Telefono: +39 02 2399 4505 – Fax: +39 02 2399 4568
