AMSI AGR Short Course Winter 2013

Variational analysis and metric regularity theory

Prof. Emeritus Alexander Ioffe, Technion, Israel

Host venue
University of Newcastle (CARMA)


The University of Newcastle is offering a short course in the period 16 - 19 July 2013, entitled Variational analysis and metric regularity theory. The course is open to postgraduate students, honours students and researchers who have access to Access Grid facilities.

If you are interested in participating, please register by sending an email to by 30 June with the following information: your full name, email address, University affiliation, and postal address.Overview of Course Content The classical regularity theory is centred around the implicit and Lyusternik-Graves theorems, on the one hand, and the Sard theorem and transversality theory, on the other. The theory (and a number of its applications to various problems of variational analysis) to be discussed in the course deals with similar problems for non-differentiable and set-valued mappings. This theory grew out of demands that came from needs of (mainly) optimization theory and subsequent understanding that some key ideas of the classical theory can be naturally expressed in purely metric terms without mention of any linear and/or differentiable structures.

Topics to be covered
The "theory" part of the course consists of five sections:

  1. Classical theory;
  2. Metric "phenomenological" theory;
  3. Metric infinitesimal theory (with the concept of "slope" of DeGiorgi-Marino-Tosques at the centre);
  4. Banach theory (with subdifferentials and coderivatives as the main instrument of analysis);
  5. Finite dimensional theory (mainly mappings with special structures, e.g. semi-algebraic, and non-smooth extensions of the Sard theorem and transversality theory). In the second part of the course (some or all of) the following applications will be discussed:
  6. Metric fixed point theory (with emphasis on two mappings models, e.g. F:X\to Y and G:Y\to X);
  7. Subregularity, exact penalties and general approach to necessary optimality conditions (optimality alternative);
  8. Stability of solutions of systems of convex inequalities;
  9. Curves of steepest descent for non-differentiable functions;
  10. Von Neumann's method of alternate projections for nonconvex sets;
  11. Tame optimization and generically good behaviour;
  12. Mathematical economics: extension of Debreu's stability theorem for non-convex and non-smooth utilities.

Formally, for understanding of the course basic knowledge of functional analysis plus some acquaintance with convex analysis and nonlinear analysis in Banach spaces (e.g. Frechet and Gateaux derivatives, implicit function theorem) will be sufficient. Understanding of the interplay between analytic and geometric concepts would be very helpful.
