• #### An Extension Problem and Trace Hardy Inequality for the Sublaplacian on H-Type Groups ﻿

[OWP-2017-20] (Mathematisches Forschungsinstitut Oberwolfach, 2017-07-24)
In this paper we study the extension problem for the sublaplacian on a H-type group and use the solutions to prove trace Hardy and Hardy inequalities for fractional powers of the sublaplacian.
• #### Holomorphic automorphic forms and cohomology ﻿

[OWP-2014-07] (Mathematisches Forschungsinstitut Oberwolfach, 2014-04-25)
We investigate the correspondence between holomorphic automorphic forms on the upper half-plane with complex weight and parabolic cocycles. For integral weights at least 2 this correspondence is given by the Eichler integral. ...
• #### Invariant Four-forms and Symmetric Pairs ﻿

[OWP-2012-03] (Mathematisches Forschungsinstitut Oberwolfach, 2012-04-24)
We give criteria for real, complex and quaternionic representations to define $s$-representations, focusing on exceptional Lie algebras defined by spin representations. As applications, we obtain the classification of ...
• #### On Weakly Complete Universal Enveloping Algebras of pro-Lie Algebras ﻿

[OWP-2020-10] (Mathematisches Forschungsinstitut Oberwolfach, 2020-04-27)
• #### Real group orbits on flag ind-varieties of SL (∞, C) ﻿

[OWP-2016-01] (Mathematisches Forschungsinstitut Oberwolfach, 2016-05-10)
We consider the complex ind-group $G=SL (\infty, \mathbb{C})$ and its real forms $G^0=SU(\infty,\infty)$, $SU(p,\infty)$, $SL(\infty,\mathbb{R})$, $SL(\infty,\mathbb{H})$. Our main object of study are the $G^0$-orbits on ...
• #### Time and band limiting for matrix valued functions, an example ﻿

[OWP-2015-08] (Mathematisches Forschungsinstitut Oberwolfach, 2015-07-29)
The main purpose of this paper is to extend to a situation involving matrix valued orthogonal polynomials and spherical functions, a result that traces its origin and its importance to work of Claude Shannon in laying the ...
• #### Torsion-free Covers of Solvable Minimax Groups ﻿

[OWP-2015-15] (Mathematisches Forschungsinstitut Oberwolfach, 2015-11-18)
We prove that every finitely generated solvable minimax group can be realized as a quotient of a torsion-free solvable minimax group. This result has an application to the investigation of random walks on finitely generated ...
