Six leading experts lecture on a wide spectrum of recent results on the
subject of the title, providing both a solid reference and deep insights
on current research activity. Michael Cowling presents a survey of
various interactions between representation theory and harmonic analysis
on semisimple groups and symmetric spaces. Alain Valette recalls the
concept of amenability and shows how it is used in the proof of rigidity
results for lattices of semisimple Lie groups. Edward Frenkel describes
the geometric Langlands correspondence for complex algebraic curves,
concentrating on the ramified case where a finite number of regular
singular points is allowed. Masaki Kashiwara studies the relationship
between the representation theory of real semisimple Lie groups and the
geometry of the flag manifolds associated with the corresponding complex
algebraic groups. David Vogan deals with the problem of getting unitary
representations out of those arising from complex analysis, such as
minimal globalizations realized on Dolbeault cohomology with compact
support. Nolan Wallach illustrates how representation theory is related
to quantum computing, focusing on the study of qubit entanglement.
