Shlyakhtenko will study classes of operator algebras arising in connectionwith Voiculescu's free probability theory. The main emphasis of thisresearch is placed on the study of operator-valued free randomvariables and operator algebras that they generate. Analysis of thesevon Neumann algebras is intimately tied with the goal ofclassification of free Araki-Woods factors, which are free probabilityanalogs of ITPFI type III factors. Such analysis is also importantfor understanding of subfactors and automorphisms of amalgamated freeproduct algebras. One of the goals of the present research is todevelop free entropy-based techniques for dealing with operator-valuedrandom variables.Free probability theory is a highly non-commutative parallel to basicprobability theory. Matrix-valued random variables (such as randommatrices) naturally fit in the non-commutative probability framework;the asymptotic behavior of large random matrices is well-modeled bymatrix-valued free random variables. Applications are in mathematicsto the theory of operator algebras, subfactors, ergodic theory, aswell as the theory of random matrices, which have connections withcertain physical models.

Shlyakhtenko将研究类算子代数所产生的连接Voiculescu的自由概率论。 本研究的主要重点是研究算子值自由随机变量及其生成的算子代数。 这些evon Neumann代数的分析与自由Araki-Woods因子的分类目标密切相关，自由Araki-Woods因子是ITPFI III型因子的自由概率类似物。 这种分析对于理解合并自由积代数的子因子和自同构也很重要。 本研究的目标之一是发展基于自由熵的技术来处理算子值随机变量，自由概率论是与基本概率论高度非交换的并行理论。 矩阵值随机变量（如随机矩阵）自然适合于非交换概率框架;大型随机矩阵的渐近行为可以很好地由矩阵值自由随机变量建模。 应用在代数学中的算子代数理论，子因子，遍历理论，以及随机矩阵理论，这些理论与某些物理模型有联系。
