Queer Poisson brackets
Daniel Beltita, Tomasz Goliński, Alice-Barbara Tumpach
We give a method to construct Poisson brackets on Banach manifolds~, for which the value of at some point may depend on higher order derivat…
Coadjoint orbits in representation theory of pro-Lie groups
Daniel Beltita, Amel Zergane
We present a one-to-one correspondence between equivalence classes of unitary irreducible representations and coadjoint orbits for a class of pro-Lie groups including all connected…
Nonlinear oblique projections
Ingrid Beltita, Daniel Beltita
We construct nonlinear oblique projections along subalgebras of nilpotent Lie algebras in terms of the Baker-Campbell-Hausdorff multiplication. We prove that these nonlinear projec…
Covariant representations for possibly singular actions on C*-algebras
Daniel Beltita, Hendrik Grundling, Karl-Hermann Neeb
Singular actions on C*-algebras are automorphic group actions on C*-algebras, where the group need not be locally compact, or the action need not be strongly continuous. We study t…
Topological aspects of group -algebras
Ingrid Beltita, Daniel Beltita
We discuss basic topological properties of unitary dual spaces of nilpotent Lie groups, using some ideas from operator algebras and their noncommutative dimension theory. The gener…
Quasidiagonality of -algebras of solvable Lie groups
Ingrid Beltita, Daniel Beltita
We characterize the solvable Lie groups of the form , whose -algebras are quasidiagonal. Using this result, we determine the connected simply…
