Title : A criterion for quick convergence of averaged projections in Banach spaces
Speaker : Izhar Oppenheim, BGU
Place : Room 814, Amado Mathematics Building, Technion

Given several subspaces $V_1,…,V_N$  in a Hilbert space and a point $x$, there are several algorithms for finding the orthogonal projection of $x$ on the intersection of $V_1,…,V_N$ given the orthogonal projections on each of the subspaces $V_1,…,V_N$.

I will only focus on one of these algorithms called the averaged projection method (which is a variant of the alternating projection method of von Neumann). It was shown that this algorithm either converges “very slowly” or “very quickly” and that one can assure quick convergence by bounding the (Friedrichs) angles between the subspaces (several results of this flavor were given by several authors).

In my talk, I will show how to generalize the notion of the Friedrichs angle for (linear) projections in Banach spaces in order to get a criterion for quick convergence of the averaged projection method in Banach spaces. This result does not require the projections to be of norm 1 (although the norm should be sufficiently close to 1) and therefore gives new results even in the Hilbert space setting for non-orthogonal (linear) projections.

Mostly Markov Mixing

Summer Workshop For Graduate Students

(and Post-Docs and Gutsy Undergrads)

Sunday-Wednesday 30.8.15 - 2.9.15

Followed by: Workshop for Researchers (and Students)

Thursday 3.9.15

Technion, Haifa, Israel

Registration is now closed. 

The workshop will focus on topics connected to and arising from the problem of calculating the mixing rate for Markov processes on large finite state spaces as the size of the state space tends to infinity.

Featured Mini-Courses:

Persi Diaconis, Stanford University

Yuval Peres, Microsoft, Redmond, WA

Additional Lectures:

Pietro Caputo, University of Rome 3

Elchanan Mossel, University of California, Berkeley

Perla Sousi, University of Cambridge

Johan Jonasson, Chalmers University of Technology

The conference will end on Thursday the 3rd of September and NOT on Friday the 4th of September!

Organizers: Ross Pinsky, Eddie Mayer-Wolf, Nick Crawford
