A spatial impedance controller for robotic manipulation [PDF]

, 1997
Mechanical impedance is the dynamic generalization of stiffness, and determines interactive behavior by definition. Although the argument for explicitly controlling impedance is strong, impedance control has had only a modest impact on robotic ...

CONFORMAL INFINITESIMAL TRANSFORMATIONS IN AN ALMOST r-CONTACT HYPERBOLIC PRODUCT MANIFOLD

Demonstratio Mathematica, 1986
The authors give necessary and sufficient conditions for a vector field to be an infinitesimal conformal transformation in an almost r-contact hyperbolic manifold defined by \textit{K. K. Dube} and \textit{R. Niwas} [Demonstr. Math. 11, 887-897 (1978; Zbl 0402.53020)].

Symmetries and pre-metric electromagnetism [PDF]

, 2005
The equations of pre-metric electromagnetism are formulated as an exterior differential system on the bundle of exterior differential 2-forms over the spacetime manifold.

Infinitesimal contact transformations and their applications to abstract growth patterns [PDF]

Quarterly of Applied Mathematics, 1980
Several abstract mathematical models of two-dimensional objects or “organisms” are introduced. The objects are abstractions, created by the combination of pattern-theoretic generators. They are deformed by what are shown to be infinitesimal contact transformations.

Variational Theory of Balance Systems [PDF]

, 2009
In this work we apply the Poincare-Cartan formalism of the Classical Field Theory to study the systems of balance equations (balance systems). We introduce the partial k-jet bundles of the configurational bundle and study their basic properties: partial ...

Anomalies and WZW-term of two-flavour QCD [PDF]

, 2000
The U(2)_R x U(2)_L symmetry of QCD with two massless flavours is subject to anomalies which affect correlation functions involving the singlet currents A^0_\mu or V^0_\mu. These are relevant for pion-photon interactions, because - for two flavours - the

Invariants of pseudogroup actions: Homological methods and Finiteness theorem [PDF]

, 2005
We study the equivalence problem of submanifolds with respect to a transitive pseudogroup action. The corresponding differential invariants are determined via formal theory and lead to the notions of k-variants and k-covariants, even in the case of non ...

Hidden Symmetries of the Principal Chiral Model Unveiled [PDF]

, 1996
By relating the two-dimensional U(N) Principal Chiral Model to a simple linear system we obtain a free-field parametrisation of solutions. Obvious symmetry transformations on the free-field data give symmetries of the model. In this way all known `hidden
