Differential geometry on Hopf algebras and quantum groups [PDF]
, 1994 The differential geometry on a Hopf algebra is constructed, by using the basic axioms of Hopf algebras and noncommutative differential geometry. The space of generalized derivations on a Hopf algebra of functions is presented via the smash product, and used to define and discuss quantum Lie algebras and their properties.

Fixed point subalgebras of Weil algebras: from geometric to algebraic questions [PDF]
arXiv, 2010 The paper is a survey of some results about Weil algebras applicable in differential geometry, especially in some classification questions on bundles of generalized velocities and contact elements. Mainly, a number of claims concerning a form of fixed points subalgebras of various Weil algebra is demonstrated.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This article presents the Multi‐Axial Subassemblage Testing facility of ETH Zurich, Switzerland (ETHZ‐MAST) for quasi‐static testing and hybrid simulation (HS) of large‐scale structural components and assemblies. The ETHZ‐MAST features a 6‐degrees‐of‐freedom (DOFs, 3 translations and 3 rotations) loading system based on a steel crosshead and ...

Dualities of deformed N = 2 $$ \mathcal{N}=2 $$ SCFTs from link monodromy on D3-brane states
Journal of High Energy Physics, 2017 We study D3-brane theories that are dually described as deformations of two different N = 2 $$ \mathcal{N}=2 $$ superconformal theories with massless monopoles and dyons. These arise at the self-intersection of a seven-brane in F-theory, which cuts out a

Differential Chow Form for Projective Differential Variety
, 2011 In this paper, a generic intersection theorem in projective differential algebraic geometry is presented. Precisely, the intersection of an irreducible projective differential variety of dimension d>0 and order h with a generic projective differential ...

A sectional curvature for statistical structures [PDF]
arXiv, 2015 A new type of sectional curvature is introduced. The notion is purely algebraic and can be located in linear algebra as well as in differential geometry.

Energy Science &Engineering, EarlyView.ABSTRACT This paper proposes an ejector‐expansion refrigeration cycle (EERC) with two evaporating temperatures to recover partial expansion work and greatly reduces the throttling loss of the other expansion valve connected to the evaporator compared with the conventional bievaporator refrigeration cycle (CBEC).

The Chemical Record, Volume 22, Issue 12, December 2022., 2022 Roald Hoffmann was the perfect theoretical chemist to collaborate with R. B. Woodward on the Principle of Conservation of Orbital Symmetry. This essay presents Hoffmann's capabilities as of May 5, 1964. Abstract Abstract: Why was it that Roald Hoffmann was the perfect collaborator for R. B.

Energy Science &Engineering, EarlyView.ABSTRACT This study investigates double‐diffusive transport and entropy generation in a wavy cylindrical enclosure containing Cu─H2O Casson nanofluid under magnetic field and thermal radiation effects. The governing equations were solved numerically using the finite element method with Galerkin formulation.
