text: "Given a geometrically finite hyperbolic surface of infinite volume it is
a\r\nclassical result of Patterson that the positive Laplace-Beltrami operator
has\r\nno $L^2$-eigenvalues $\\geq 1/4$. In this article we prove a generalization
of\r\nthis result for the joint $L^2$-eigenvalues of the algebra of commuting\r\ndifferential
operators on Riemannian locally symmetric spaces $\\Gamma\\backslash\r\nG/K$ of
higher rank. We derive dynamical assumptions on the $\\Gamma$-action on\r\nthe
geodesic and the Satake compactifications which imply the absence of the\r\ncorresponding
principal eigenvalues. A large class of examples fulfilling these\r\nassumptions
are the non-compact quotients by Anosov subgroups."

an innovative solution to a variety of problems in many fields. Automated control

text: In this article we prove meromorphic continuation of weighted zeta functions
in the framework of open hyperbolic systems by using the meromorphically continued
restricted resolvent of Dyatlov and Guillarmou (2016). We obtain a residue formula
proving equality between residues of weighted zetas and invariant Ruelle distributions.
We combine this equality with results of Guillarmou, Hilgert and Weich (2021)
in order to relate the residues to Patterson-Sullivan distributions. Finally we
provide proof-of-principle results concerning the numerical calculation of invariant
Ruelle distributions for 3-disc scattering systems.

text: "We present a numerical algorithm for the computation of invariant Ruelle\r\ndistributions
on convex co-compact hyperbolic surfaces. This is achieved by\r\nexploiting the
connection between invariant Ruelle distributions and residues\r\nof meromorphically
continued weighted zeta functions established by the authors\r\ntogether with
Barkhofen (2021). To make this applicable for numerics we express\r\nthe weighted
zeta as the logarithmic derivative of a suitable parameter\r\ndependent Fredholm
determinant similar to Borthwick (2014). As an additional\r\ndifficulty our transfer
operator has to include a contracting direction which\r\nwe account for with techniques
developed by Rugh (1992). We achieve a further\r\nimprovement in convergence speed
for our algorithm in the case of surfaces with\r\nadditional symmetries by proving
and applying a symmetry reduction of weighted\r\nzeta functions."

text: Erfolg und Misserfolg eines Unternehmens werden maßgeblich durch getroffene
Entscheidungen beeinflusst. Daher verlassen sich Entscheider oft auf Entscheidungsunterstützungssysteme,
die durch Datensimulation, -optimierung und -visualisierung bei der Identifizierung
von geeigneten Entscheidungen unterstützen. Für eine optimale Unterstützung muss
ein Entscheidungsunterstützungssystem (EUS) jedoch auf den Entscheidungsprozess
eines Entscheiders abgestimmt sein und verfügbare Daten, Optimierungsziele, persönliche
Präferenzen sowie weitere Einflussfaktoren berücksichtigen. EUS-Entwickler können
aufgrund der Komplexität und Volatilität von Geschäftsumgebungen allerdings nicht
alle potenziellen Entscheidungsprozesse während des Entwurfs eines EUS vorhersehen,
wodurch ein EUS einem Entscheider häufig nur unzureichende Anpassungsmöglichkeiten
an den individuellen Entscheidungsprozess bietet. Die Einzelanfertigung eines
EUS, das auf einen Entscheidungsprozess zugeschnitten ist, ist ein kosten- und
zeitintensives Unterfangen aufgrund der begrenzten Verfügbarkeit von Softwareentwicklern
oder Missverständnissen zwischen Entwicklern und Entscheidern während der Entwicklung.
Daher geben sich Entscheider möglicherweise mit einem handelsüblichen EUS zufrieden,
das nicht vollständig mit ihrem Entscheidungsprozess übereinstimmt, suboptimale
Entscheidungen begünstigt und so den Unternehmenserfolg negativ beeinflusst. In
dieser Arbeit wird ein Ansatz vorgeschlagen, der es Entscheidern ermöglicht, selbst
maßgeschneiderte Entscheidungsunterstützungssysteme zu entwickeln und so die Diskrepanz
zwischen benötigter und tatsächlicher Entscheidungsunterstützung zu vermeiden.
Dazu stellen EUS-Entwickler einen Teil der EUS-Funktionalität als wiederverwendbare
Software-Dienste bereit ...

text: 'Decision making significantly determines the success or failure of a business.
This motivates decision makers to rely on decision support systems for assistance
in identifying high-quality decisions using data simulation, optimization, and
visualization. However, for optimal assistance, a decision support system (DSS)
must align with the decision-making process of a decision maker, which is characterized
by available data, optimization goals, personal preferences, and other influences.
Unfortunately, the increasing complexity and volatility of business environments
prevent DSS developers to anticipate all potential decision-making processes during
DSS design, and consequently, to provide decision makers with sufficient customization
options. Commissioning a DSS that is tailored to a decision-making process is
a cost- and time-intensive undertaking due to limited developer availability or
misunderstandings between developers and decision makers. As a result, decision
makers may settle for an off-the-shelf DSS that does not fully align with their
decision-making process and potentially results in suboptimal decisions, thereby
impairing business success.This thesis proposes an approach that enables decision
makers to create tailored decision support systems themselves, thereby avoiding
the aforementioned misalignment between provided and required decision support.
The approach expects DSS developers to provide partial DSS functionality in the
form of reusable software services. Using a low-code approach, non-programmers
can then compose these services into a holistic DSS by modeling a decision-making
process with the help of an assistance system. The contribution of the thesis
is fourfold: First, the thesis explains how to design a service repository to
capture available decision support services for the encompassing application domain.

text: "We consider the quantum dynamics of a many-fermion system in $\\mathbb R^d$\r\nwith
an ultraviolet regularized pair interaction as previously studied in [M.\r\nGebert,
B. Nachtergaele, J. Reschke, and R. Sims, Ann. Henri Poincar\\'e 21.11\r\n(2020)].
We provide a Lieb-Robinson bound under substantially relaxed\r\nassumptions on
the potentials. We also improve the associated one-body\r\nLieb-Robinson bound
on $L^2$-overlaps to an almost ballistic one (i.e., an\r\nalmost linear light
cone) under the same relaxed assumptions. Applications\r\ninclude the existence
of the infinite-volume dynamics and clustering of ground\r\nstates in the presence
of a spectral gap. We also develop a fermionic continuum\r\nnotion of conditional
expectation and use it to approximate time-evolved\r\nfermionic observables by
local ones, which opens the door to other applications\r\nof the Lieb-Robinson
bounds."
