Highest-weight Theory: Verma Modules
We will now turn to the problem of classifying and constructing all finitedimensional representations of a complex semi-simple Lie algebra (or, equivalently, of a compact Lie group). It turns out that such representations can be characterized by their “highest-weight”. The first method we’ll consider is purely Lie-algebraic, it begins by constructing a universal representation with a given high...
متن کاملCharacterization of Simple Highest Weight Modules
We prove that for simple complex finite dimensional Lie algebras, affine Kac-Moody Lie algebras, the Virasoro algebra and the Heisenberg-Virasoro algebra, simple highest weight modules are characterized by the property that all positive root elements act on these modules locally nilpotently. We also show that this is not the case for higher rank Virasoro and for Heisenberg algebras.
متن کاملLaplace transform and unitary highest weight modules
The unitarizable modules in the analytic continuation of the holomorphic discrete series for tube type domains are realized as Hilbert spaces obtained through the Laplace transform.
متن کاملCriteria for the Unitarizability of Some Highest Weight Modules
For a linear semisimple Lie group we obtain a necessary and sufficient condition for a highest weight module with non-singular infinitesimal character to be unitarizable.
متن کاملUnitarity of Highest Weight Modules for Quantum Groups
We determine the highest weights that give rise to unitarity when q is real. We further show that when q is on the unit circle and q 6= ±1, then unitary highest weight representations must be finite dimensional and q must be a root of unity. We analyze the special case of the “ladder” representations for su(m,n). Finally we show how the quantized Ladder representations and their analogues for o...
