# WWTF - Vienna Research Groups for Young Investigators 2017: Expander Graphs: Constructions, Generalisations, and Applications

These are highly connected sparse graphs useful in many areas of mathematics and computer science.
The interest to find new explicit constructions of expanders is motivated by applications in network design, coding theory, cryptography, compressive sensing, metric geometry, and derandomization of algorithms, etc. Such constructions often require deep pure mathematical results, e.g. methods of group representation theory. Our research is both on new constructions of expanders using geometric, combinatorial, computational, and analytic group theory and on further applications of expanders.

Univ.-Prof. Goulnara Arzhantseva
goulnara.arzhantseva$univie.ac.at #### Position: Applications are being invited for outstanding early-career scientists (2-8 years post PhD), interested in building up their first independent research group in the field of "Mathematics" at the University of Vienna. The aim of this announcement is to source exceptional candidates, who, once selected, will then go on to submit an application together with an experienced scientist at the University of Vienna, to the current call for young investigators by the Vienna Science and Technology Fund (WWTF): https://www.wwtf.at/upload/VRG17_web.pdf. In the case of a successful funding decision, the research group will be financed for 6-8 years, with up to 1.6 million EUR being provided by the WWTF, supplemented by an additional contribution from the University itself. After a successful interim evaluation, the University of Vienna will offer the group leader a tenure-track position. #### Requirements: Applicants should have exceptional promise, or a proven record of research achievement, within the field of mathematics. They should also provide strong evidence of their potential to make a significant contribution to substantial state-of-the-art scientific research questions in this particular research field. Female applicants are explicitly encouraged to apply. #### Application procedure: Interested PostDoc candidates should get in touch with the scientific contact. Please send your CV with publication list, list of research projects, teaching activities (evaluations, if available) and supervised PhD students to projektservice.mathematik$univie.ac.at by no later than 30th April 2017.
