"The empirical pair process and a CLT for non-symmetric U-statistics." Abstract. In my talk I will introduce and analyze the empirical pair process, and show how this concept can be applied to obtain a central limit theorem for non-symmetric U-statistics (joint work with Sergey Utev). |

"On the existence of infinite volume tree polymer limits" Abstract. Existence of an infinite volume tree polymer model is discussed in the case of weak and strong disorder, and some results related to recent speculation by Yuval Peres and computer simulations by Torrey Johnson will be indicated -- leading to further speculations. |

"Monotone Iterated Function Systems and Self-Reinforced Learning Models." Abstract. The early years of the decade starting with 1950s saw the development of learning models which were Markov chains arising as iteration of random processes with monotone properties. There were papers by Bush and Mosteller, T.Harris, and S.Karlin who studied Markov Chains with the structure of iterated random composition of monotone functions on an interval. These ideas were predecessors to g-Martingales of M.Keane, and in turn led to Iterated Function Systems. We take this idea and generalize it to associative structure, i.e. those in which past repetitions of a behavior make this behavior more likely in the future. From this, we can get Central Limit Theorems, even in the absence of uniform mixing assumptions. This is seen as falling into the L_1 / L_2 dichotomy of analysis. |
