We will review basics of the theory and show that the barcode associated to a linear combination of Laplace-Beltra mi eigenfunctions on a smooth surface satisfies certain restrictions. Appl ications to C^0-approximation of a function by linear combinations of Lapl ace-Beltrami eigenfunctions will also be discussed. The talk is based on a joint work with Iosif Polterovich and Leonid Polterovich.\n DTSTART:20180119T160000Z DTEND:20180119T170000Z LOCATION:Room PK-5115 \, CA\, Pavillon President-Kennedy SUMMARY:Vukasin Stojislavljevic (Université de Tel Aviv) URL:/mathstat/channels/event/vukasin-stojislavljevic-u niversite-de-tel-aviv-283889 END:VEVENT END:VCALENDAR
