On the multi-Koszul property for connected algebras
(Univ Bielefeld, 2013-12)
In this article we introduce the notion of multi-Koszul algebra for the case of a locally finite dimensional nonnegatively graded connected algebra, as a generalization of the notion of (generalized) Koszul algebras defined ...
Hochschild and cyclic homology of Yang–Mills algebras
(De Gruyter, 2012-04)
The aim of this article is to present a detailed algebraic computation of the Hochschild and cyclic homology groups of the Yang–Mills algebras YM(n) (n ∈ ℕ≧2) defined by A. Connes and M. Dubois-Violette in [8], continuing ...

ON NONSYMMETRIC THEOREMS FOR (H, G)-COINCIDENCES
(JULIUSZ SCHAUDER CTR NONLINEAR STUDIESTORUN, 2009)
Let X be a compact Hausdorff space, phi: X -> S(n) a continuous map into the n-sphere S(n) that induces a nonzero homomorphism phi*: H(n)(S(n); Z(p)) -> H(n)(X; Z(p)), Y a k-dimensional CW-complex and f: X -> a continuous ...
ABELIANIZED OBSTRUCTION FOR FIXED POINTS OF FIBER-PRESERVING MAPS OF SURFACE BUNDLES
(JULIUSZ SCHAUDER CTR NONLINEAR STUDIES, 2009)
Let f: M -> M be a fiber-preserving map where S -> M -> B is a bundle and S is a closed surface. We study the abelianized obstruction, which is a cohomology class in dimension 2, to deform f to a fixed point free map by a ...
Locally conformal symplectic structures on Lie algebras of type i and their solvmanifolds
(De Gruyter, 2019-05-01)
We study Lie algebras of type I, that is, a Lie algebra g where all the eigenvalues of the operator ad X are imaginary for all X g. We prove that the Morse-Novikov cohomology of a Lie algebra of type I is trivial for any ...
Sobre o funcional de ação mínima de Mather: propriedades genéricas e diferenciabilidade
(Universidade Federal de Minas GeraisUFMG, 2013-01-22)
In this thesis we present some generic properties and its consequences to the dynamics of the Aubry set that appear in the Mathers theory about Tonelli Lagrangians and Hamiltonian systems. We also study conditions for ...
Charges and fluxes in Maxwell theory on compact manifolds with boundary
(Springer, 2006-10-01)
We investigate the charges and fluxes that can occur in higher-order Abelian gauge theories defined on compact space-time manifolds with boundary. The boundary is necessary to supply a destination to the electric lines of ...
Abelianized obstruction for fixed points of fiber-preserving maps of surface bundles
(Juliusz Schauder Ctr Nonlinear Studies, 2009-06-01)
Let f: M -> M be a fiber-preserving map where S -> M -> B is a bundle and S is a closed surface. We study the abelianized obstruction, which is a cohomology class in dimension 2, to deform f to a fixed point free map by a ...
