Title: Transversality, subtransversality and intrinsic transversality of pairs of sets
Date and time: Friday, 3 March 2017, 3:00-4:00pm
Location: Building 8 Level 9 Room 66 (AGR) RMIT City campus
Abstract: Several transversality properties of pairs of sets and their role in the convergence analysis of fundamental projection algorithms will be discussed. Dual characterizations of the properties in terms of Fréchet, limiting and proximal normals will be provided. The new ‘intrinsic transversality’ property will be examined.
The talk is based on the following recent papers.

Bio: Alex Kruger received his PhD in mathematics from the Belarusian State University in 1981. Prior to joining University of Ballarat in 2003, he had worked at several universities and research institutions in Minsk, Belarus and also spent 4 months doing research as a Fulbright Scholar at Indiana University South Bend, USA. He has published about 85 papers in the fields of generalized differentiation, optimisation theory and variational analysis.
