SUMMARY:Twisted representations of product systems of C*-correspondences: W
 old decomposition and unitary extensions (Suryawanshi)
DESCRIPTION:Lecturer:Mansi Suryawanshi (Technion)\n Location:Amado 814 and 
 zoom\n We investigate Wold-type decompositions and unitary extension probl
 ems for multivariable isometric covariant representations associated with 
 product systems of C*-correspondences. First\, we establish an operator-t
 heoretic characterization for the existence of a Wold decomposition for th
 e k-tuple consisting of isometric covariant representations of a C*-corre
 spondences. We then introduce twisted and doubly twisted covariant represe
 ntations of product systems. For doubly twisted isometric representations\
 , we prove the existence of a Wold decomposition\, recovering earlier resu
 lts for doubly commuting representations as special cases. We further obta
 in explicit descriptions of the resulting Wold summands and develop concre
 te Fock-type models realizing each component. We present non-trivial examp
 les of these families. Finally\, we construct unitary extensions via a dir
 ect-limit procedure. As applications\, we obtain unitary extensions for se
 veral previously studied classes of operator tuples\, including doubly twi
 sted\, doubly non-commuting\, and doubly commuting isometries\, and for a 
 special class of doubly twisted representations of a product system.\n htt
