Seminari dei Baby Geometri
by tardini＠student.dm.unipi.it 25 Feb '16

25 Feb '16

Cari tutti, Martedì 1 Marzo alle 14:30 presso l'aula seminari del DM riprendono i seminari dei Baby Geometri. Lo speaker sarà Kirill Kuzmin (Università di Pisa) e terrà un seminario dal titolo: "Relativa Iperbolicità e Rigidità Quasi Isometrica" di cui riporto l'abstract: In questo seminario esploreremo alcune proprietà di gruppi e di varietà invarianti per quasi isometria. Tratteremo in particolare oggetti che si possono costruire a partire da oggetti più semplici e ci concentreremo su quelli che possiedono la proprietà di ``Relativa iperbolicità'' che generalizza l'idea di iperbolicità di Gromov, che esprime una condizione di curvatura negativa su larga scala, a contesti dove tale proprietà di curvatura non è più valida. Tutti siete invitati a partecipare. A seguire: 08 Marzo, Daniele Celoria 15 Marzo, Daniele Angella 22 Marzo, Chinh Lu 05 Aprile, Luigi Caputi 07 Aprile, Maurizio Parton Per saperne di più sui prossimi seminari scrivete ad uno degli organizzatori o consultate la pagina: http://gecogedi.dimai.unifi.it/seminars/ Mailing-list: babygeom(a)poisson.phc.unipi.it Saluti, Nicoletta Tardini e Carlo Collari

Seminario oggi
by Bruno Martelli 17 Feb '16

17 Feb '16

Buondi, con colpevole ritardo vi ricordo il seminario di geometria di oggi, in aula seminari alle 15. Bruno Speaker: Leone Slavich Titolo: Varietà tetraedrali geometricamente bordanti Abstract: Introdurremo una costruzione che permette di realizzare alcune 3-varietà iperboliche tassellate da tetraedri ideali regolari come ipersuperfici geodetiche in una 4-varietà iperbolica. Come applicazione, mostreremo che il complementare del nodo figura 8 è realizzabile come bordo totalmente geodetico di una 4-varietà iperbolica. La costruzione è di natura essenzialmente combinatoria, e sfrutta le proprietà di un politopo di Coxeter iperbolico di dimensione 4: la 5-cella rettificata.

There is also a requirement to teach up to four sets of undergraduate or graduate classes per year, determined by the demand for classes in specific areas. Applicants should have a PhD awarded or submitted (at the time of taking up the position) in mathematics or a related discipline, and be able to demonstrate a strong background in gauge-theoretic techniques in low-dimensional topology, preferably Heegaard Floer homology, and a research focus on 4-dimensional applications. A good publication record judged by the stage of his/her career, and the ability to work together with others as part of a research team are also essential. Please direct informal enquiries to the Administrative Assistant (email: vacancies(a)maths.ox.ac.uk), quoting vacancy reference 122188. Applicants should read the job description before writing their application. You will be required to upload a letter setting out how you meet the selection criteria, a curriculum vitae including full list of publications, a statement of research interests and the contact details of three referees as part of your online application. (NOTE: Applicants are responsible for contacting their referees and making sure that their letters are received by the closing date). Applications for this vacancy are to be made online. To apply for this post and for further details, including the job description and selection criteria, please click on the link below https://www.recruit.ox.ac.uk/pls/hrisliverecruit/erq_jobspec_version_4.jobs… Only applications received before 12:00 noon UK time on Monday 14th March 2016 can be considered.

Buongiorno, oggi alle ore 15 in sala seminari del dipartimento di matematica si svolgera' il seguente seminario: Serap Gürer (Istanbul University): Diffeological controlled pseudomanifolds. Abstract: In this talk we show that diffeological De Rham cohomology of a controlled pseudo manifold equipped with quotient diffeology is isomorphic to the singular cohomology with real coefficients of controlled pseudo manifold Moreover, we shall show that diffeological differential forms of normalisation of a controlled pseudo manifold are isomorphic to zero perverse differential forms of their diffeological unfolding.

preliminary meeting (Feb 01) - PhD course on complex Monge-Ampère by C. Lu
by Daniele Angella 13 Jan '16

13 Jan '16

Dear all, a PhD course on "Complex Monge-Ampère equations on compact Kähler manifolds" will be taught by Chinh H. Lu in Firenze. The course will take place between February and May 2016, at Dipartimento di Matematica e Informatica "Ulisse Dini" of Università di Firenze. You find here below the abstract. A first preliminary meeting is scheduled for: monday February 01, 2016, at 13:00. The calendar of the course will be scheduled in that occasion. Further and updated informations will be available at the webpage of the event on GeCoGeDi <https://gecogedi.dimai.unifi.it/event/294/>. Please, feel free to contact us if you are interested in attending the course. And to forward this message to whoever might be interested in it. The course is supported by the project SIR2014 "Analytic aspects in complex and hypercomplex geometry" <https://sites.google.com/site/danieleangella/projects/anhyc> and it is part of the PhD program in Mathematics of Università di Firenze <http://www.dimai.unifi.it/vp-26-dottorati.html>. Best regards, Daniele Angella, Simone Calamai ---------------------------- Title: "Complex Monge-Ampère equations on compact Kähler manifolds" Number of hours: 30h / 6 CFU (20h by Chinh, 10h of preparation in complex geometry by Daniele) Period: starting from the middle of February until middle of May Place: Firenze Program: The aim of the course is to survey recent important results concerning the complex Monge-Ampère equation on compact Kähler manifolds. We first present the proof of the Calabi conjecture by reducing it to a complex Monge-Ampère equation and establishing a priori estimates. We then go on to develop a (global) pluripotential theory on compact Kähler manifold, focusing on the theory of (generalized) capacities and its application in proving singular uniform estimate. We also introduce a variational method to solve degenerate complex Monge-Ampère equation and study the finite energy spaces which will be recognized as the completion of the space of Kähler metircs equipped with the Mabuchi distance. The last lecture will be a more advanced talk (materials from previous lectures will be useful) on the weak Calabi flow, its large time behavior as well as some conjectures in the field. A preliminary part of the course will discuss basic results on complex and Kähler geometry. Teacher: Chinh H.
