Symmetry and Inverse Closedness for Some Banach ∗-Algebras Associated to Discrete Groups
(Tusi Mathematical Research Group, 2015)
A discrete group G is called rigidly symmetric if for every C*-algebra A the projective tensor product l(1)(G)(circle times) over capA is a symmetric Banach *-algebra. For such a group we show that the twisted crossed ...
Nonsymmetric tensor description of massive spin-2 particles in a curved background
(2017-03-30)
Massive spin-2 particles have been a subject of great interest in current research. If the graviton has a small mass, the gravitational force at large distances decreases more rapidly, which could contribute to the explanation ...
Symmetric affine surfaces with torsion
(Elsevier Science, 2019-10)
We study symmetric affine surfaces which have non-vanishing torsion tensor. We give a complete classification of the local geometries possible if the torsion is assumed parallel. This generalizes a previous result of Opozda ...
A VARIATIONAL METHOD FOR GENERATING n-CROSS FIELDS USING HIGHER-ORDER Q-TENSORS
(SIAM PUBLICATIONS, 2021)
An n-cross field is a locally defined orthogonal coordinate system invariant with respect to the hyperoctahedral symmetry group (cubic for n = 3). Cross fields are finding widespread use in mesh generation, computer graphics, ...
Neutron stars in Scalar-Tensor-Vector Gravity
(Springer, 2017-02)
Scalar-Tensor-Vector Gravity (STVG), also referred as Modified Gravity (MOG), is an alternative theory of the gravitational interaction. Its weak field approximation has been successfully used to describe Solar System ...
Nonuniqueness of the Fierz-Pauli mass term for a nonsymmetic tensor
(Amer Physical Soc, 2012-12-21)
Starting with a description of massive spin-2 particles in D = 4 in terms of a mixed symmetry tensor T-[mu nu]rho without a totally antisymmetric part (T-[[mu nu]rho] = 0), we obtain a dual model in terms of a non-symmetric ...

The dimensional reduction of linearized spin-2 theories invariant under transverse diffeomorphisms
(2021-06-01)
Here we perform the Kaluza–Klein dimensional reduction from D+ 1 to D dimensions of massless Lagrangians described by a symmetric rank-2 tensor and invariant under transverse differmorphisms (TDiff). They include the ...
