Codimension two submanifolds with 2-nonnegative curvature operator
(2008)
In this paper we obtain a classification of compact n-submanifolds of the Euclidean space Rn+2 with 2-nonnegative curvature operator.

Infinite dimensional Lie algebra associated with conformal transformations of the two-point velocity correlation tensor from isotropic turbulence
(Birkhauser VerlagBasel, 2013)
We deal with homogeneous isotropic turbulence and use the two-point velocity correlation tensor field (parametrized
by the time variable t) of the velocity fluctuations to equip an affine space K3 of the correlation vectors ...
General aspects of Gauss-Bonnet models without potential in dimension four
(IOP Publishing, 2017-07)
In the present work, the isotropic and homogenous solutions with spatial curvature k=0 of four dimensional Gauss-Bonnet models are characterized. The main assumption is that the scalar field φ which is coupled to the ...
