The impact of commuting time over educational achievement: A machine learning approachThe impact of commuting time over educatiónal achievement: a machine learning approach
(2018)
Taking advantage of georeferenced data from Chilean students, we estimate the impact of commuting time over academic achievement. As the commuting time is an endogenous variable, we use instrumental variables and fixed ...
The Toeplitz algebra on the Bergman space coincides with its commutator ideal
(Theta Foundation, 2004-12)
Let L^2-a be the Bergman space of the unit disk and T(L^2_a) be the Banach algebra generated by Toeplitz operators T_f , with f ∈ L∞. We prove that the closed bilateral ideal of T(L2a) generated by operators of the form ...
Dirac Oscillator in a Galilean Covariant Non-commutative Space
(International Journal of Theoretical Physics, 2013)
We study the Galilean Dirac oscillator in a non-commutative situation, with
space-space and momentum-momentum non-commutativity. The wave equation is obtained
via a ‘Galilean covariant’ approach, which consists in projecting ...
Duality in noncommutative topologically massive gauge field theory revisited
(Springer, 2004-05-01)
We introduce a master action in non-commutative space, out of which we obtain the action of the non-commutative Maxwell-Chern-Simons theory. Then, we look for the corresponding dual theory at both first and second order ...
