• #### Affine Space Fibrations ﻿

[OWP-2018-19] (Mathematisches Forschungsinstitut Oberwolfach, 2018-09-05)
We discuss various aspects of affine space fibrations. Our interest will be focused in the singular fibers, the generic fiber and the propagation of properties of a given smooth special fiber to nearby fibers.
• #### Categorical Linearly Ordered Structures ﻿

[OWP-2018-08] (Mathematisches Forschungsinstitut Oberwolfach, 2018-04-26)
We prove that for every computable limit ordinal $\alpha$ there exists a computable linear ordering $\mathcal{A}$ which is $\Delta^0_\alpha$-categorical and $\alpha$ is smallest such, but nonetheless for every isomorphic ...
• #### Computing Congruence Quotients of Zariski Dense Subgroups ﻿

[OWP-2018-22] (Mathematisches Forschungsinstitut Oberwolfach, 2018-10-26)
• #### Spectral Continuity for Aperiodic Quantum Systems II. Periodic Approximations in 1D ﻿

[OWP-2018-27] (Mathematisches Forschungsinstitut Oberwolfach, 2018-12-17)
The existence and construction of periodic approximations with convergent spectra is crucial in solid state physics for the spectral study of corresponding Schrödinger operators. In a forthcoming work [9] this task was ...
• #### Sur le Minimum de la Fonction de Brjuno ﻿

[OWP-2018-26] (Mathematisches Forschungsinstitut Oberwolfach, 2018-12-11)
The Brjuno function attains a strict global minimum at the golden section.
• #### The Sylow Structure of Scalar Automorphism Groups ﻿

[OWP-2018-05] (Mathematisches Forschungsinstitut Oberwolfach, 2018-03-22)
For any locally compact abelian periodic group A its automorphism group contains as a subgroup those automorphisms that leave invariant every closed subgroup of A, to be denoted by SAut(A). This subgroup is again a locally ...
