• Convolution in Dual Cesàro Sequence Spaces ﻿

[OWP-2022-20] (Mathematisches Forschungsinstitut Oberwolfach, 2022-12-16)
We investigate convolution operators in the sequence spaces $d_p$, for 1 $\leqslant p<\infty$. These spaces, for $p$ > 1, arise as dual spaces of the Cesàro sequence spaces $ces_p$ thoroughly investigated by G. Bennett. A ...
• Hutchinson's Intervals and Entire Functions from the Laguerre-Pólya Class ﻿

[OWP-2022-19] (Mathematisches Forschungsinstitut Oberwolfach, 2022-12-12)
• Coorbit Spaces and Dual Molecules: the Quasi-Banach Case ﻿

[OWP-2022-08] (Mathematisches Forschungsinstitut Oberwolfach, 2022-05-27)
This paper provides a self-contained exposition of coorbit spaces associated with integrable group representations and quasi-Banach function spaces. It extends the theory in [Studia Math., 180(3):237–253, 2007] to locally ...
• Deciding Non-Freeness of Rational Möbius Groups ﻿

[OWP-2022-07] (Mathematisches Forschungsinstitut Oberwolfach, 2022-03-22)
We explore a new computational approach to a classical problem: certifying non-freeness of (2-generator, parabolic) Möbius subgroups of SL(2, $\mathbb{Q}$). The main tools used are algorithms for Zariski dense groups and ...
• Characterization of Tropical Planar Curves up to Genus Six ﻿

[OWP-2022-06] (Mathematisches Forschungsinstitut Oberwolfach, 2022-03-16)
We provide new forbidden criterion for realizability of smooth tropical plane curves. This in turn provides us a complete classification of smooth tropical plane curves up to genus six.
• Local and Global Canonical Forms for Differential-Algebraic Equations with Symmetries ﻿

[OWP-2022-05] (Mathematisches Forschungsinstitut Oberwolfach, 2022-02-21)
Linear time-varying differential-algebraic equations with symmetries are studied. The structures that we address are self-adjoint and skew-adjoint systems. Local and global canonical forms under congruence are presented ...
• Aeppli-Bott-Chern-Massey Products, Bigraded Notions of Formality, and Non-Zero Degree Maps ﻿

[OWP-2022-04] (Mathematisches Forschungsinstitut Oberwolfach, 2022-02-15)
We introduce and study notions of bigraded formality for the algebra of forms on a complex manifold, along with their relation to higher Aeppli-Bott-Chern-Massey products which extend, in an augmented setting, the case of ...
• Some Homological Properties of Borel Type Ideals ﻿

[OWP-2022-03] (Mathematisches Forschungsinstitut Oberwolfach, 2022-02-01)
We study ideals of Borel type, including $k$-Borel ideals and $t$-spread Veronese ideals. We determine their free resolutions and their homological shift ideals. The multiplicity and the analytic spread of equigenerated ...
• Trivial Source Character Tables of SL2(q) ﻿

[OWP-2022-02] (Mathematisches Forschungsinstitut Oberwolfach, 2022-01-28)
We compute the trivial source character tables (also called species tables of the trivial source ring) of the infinite family of finite groups SL(2,q) over a large enough field of positive characteristic $\ell$ via ...
• Applications of Nijenhuis Geometry III: Frobenius Pencils and Compatible Non-Homogeneous Poisson Structures ﻿

[OWP-2022-01] (Mathematisches Forschungsinstitut Oberwolfach, 2022-01-20)
We consider multicomponent local Poisson structures of the form $\mathcal P_3 + \mathcal P_1$, under the assumption that the third order term $\mathcal P_3$ is Darboux-Poisson and non-degenerate, and study the Poisson ...
