Expanding solitons to the Hermitian curvature flow on complex Lie groups
, 2019 We investigate the algebraic structure of complex Lie groups equipped with left-invariant metrics which are expanding semi-algebraic solitons to the Hermitian curvature flow (HCF).

Roadmap on Weak Measurements in Optics
Advanced Physics Research, EarlyView.Quantum weak measurements have attracted considerable recent attention for both addressing fundamental questions in quantum mechanics and for numerous potential applications. This review aims to compile both the fundamental aspects and the ongoing metrological applications of weak measurements in the domain of quantum and classical optics in a concise ...

Geodesics in the extended Kähler cone of Calabi-Yau threefolds
Journal of High Energy Physics, 2022 We present a detailed study of the effective cones of Calabi-Yau threefolds with h 1,1 = 2, including the possible types of walls bounding the Kähler cone and a classification of the intersection forms arising in the geometrical phases.

Full‐order observer design for quadratic port‐controlled Hamiltonian systems
Asian Journal of Control, EarlyView.Abstract The full‐order observer design problem for a particular class of port‐controlled Hamiltonian systems is approached in this paper. The proposed full‐order observer scheme belongs to the structure preserving class of dynamic estimators as it preserves the natural stability properties of the approached class of systems that are useful for the ...

Scattering forms and the positive geometry of kinematics, color and the worldsheet
Journal of High Energy Physics, 2018 The search for a theory of the S-Matrix over the past five decades has revealed surprising geometric structures underlying scattering amplitudes ranging from the string worldsheet to the amplituhedron, but these are all geometries in auxiliary spaces as ...

Differential Operators on Azumaya algebra and Heisenberg algebra [PDF]
arXiv, 2000 We use the definition of differential operators on noncommutative rings given by V.Lunts and A.Rosenberg to find the differential operators on Azumaya algebras and the Heisenberg algebras.

Topics in algebra, geometry and differential equations
, 2022 The study of differential equations and the study of algebraic geometry are two disciplines within mathematics that seem to be mostly disjoint from each other. Looking deeper, however, one finds that connections do exist. This thesis gives in four chapters four examples of interesting mathematical insights that can be gained from combining the concepts

Civil Engineering Design, EarlyView.Abstract The German Research Foundation has established the priority program SPP 100+. Its subject is monitoring bridge structures in civil engineering. The data‐driven methods cluster deals with the use of measurements and their special global and local analysis methods, which complement each other in an overall multi‐scale concept in order to realize

Maximal cuts in arbitrary dimension
Journal of High Energy Physics, 2017 We develop a systematic procedure for computing maximal unitarity cuts of multiloop Feynman integrals in arbitrary dimension. Our approach is based on the Baikov representation in which the structure of the cuts is particularly simple. We examine several
