Conformally invariant differential equations and projective geometry

open access: yesJournal of Functional Analysis, 1981
AbstractWe combine harmonic analysis on certain pseudo-Riemannian symmetric spaces with results on conformally invariant linear and non-linear differential equations. This gives in many cases part of the decomposition of certain representations of the conformal group of a manifold when restricted to the isometry group.

Hot‐Film and Calorimetric Methods With Transient Heating for Measurement of High Biofluid Flow Rate

open access: yesAdvanced Functional Materials, EarlyView.
Accurate measurement of biofluid flow rate is vital for clinical diagnostics. We propose a transient heating strategy using short thermal pulses and peak temperature tracking to enhance the flow sensitivity of the hot‐Film and calorimetric methods. Simulations show how optimal heating time maximizes sensitivity across flow rates.

Conformal Dirichlet-Neumann Maps and Poincaré-Einstein Manifolds

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
A conformal description of Poincaré-Einstein manifolds is developed: these structures are seen to be a special case of a natural weakening of the Einstein condition termed an almost Einstein structure.

Superconformal quantum mechanics on Kähler cones

open access: yesJournal of High Energy Physics, 2020
We consider supersymmetric quantum mechanics on a Kähler cone, regulated via a suitable resolution of the conical singularity. The unresolved space has a u(1, 1|2) superconformal symmetry and we propose the existence of an associated quantum mechanical ...

Bootstrap bounds on closed hyperbolic manifolds

open access: yesJournal of High Energy Physics, 2022
The eigenvalues of the Laplace-Beltrami operator and the integrals of products of eigenfunctions must satisfy certain consistency conditions on compact Riemannian manifolds.

Geometry of strings and branes [PDF]

open access: yes, 2002
De elementaire-deeltjesfysica probeert de fundamentele bouwstenen van de Natuur en hun onderlinge wisselwerkingen te beschrijven. Uit experimenten is gebleken dat de elementaire deeltjes in twee klassen zijn onder te brengen: de leptonen, waaronder het ...

Exploring Curvature Effects in Direct‐Written 3D Curved Hollow Magnetic Nanoshells

open access: yesAdvanced Functional Materials, EarlyView.
Fabricated by a hybrid FEBID/CVD method, 3D PtC/Co3Fe core–shell heterostructures with engineered curvature and shell thickness exhibit complex reversal modes with axially symmetric N'eel‐type domain walls. XMCD‐PEEM combined with full‐scale micromagnetic simulations reveal how curvature and thickness govern the domain wall energy landscape and shape ...

Argyres-Douglas theories, chiral algebras and wild Hitchin characters

open access: yesJournal of High Energy Physics, 2018
We use Coulomb branch indices of Argyres-Douglas theories on S 1 × L(k, 1) to quantize moduli spaces ℳH $$ {\mathrm{\mathcal{M}}}_H $$ of wild/irregular Hitchin systems.
