D. JÄKEL, AND R. E. MARTINEZ II Here and in other sections describing positive-temperature fields, we denote β = 1 kBT as the inverse temperature.  ...  Thus, D v (k) → D v (k), and in configuration space π n D v π n = D * v . Thus, π n D v and D v π n are self-adjoint.  ...  For α, α ′ ∈ H − 1 2 (R d−1 ) and s, s ′ ∈ R, , Proof. We compute  ...

Half-flat quantum hair

Hugo García-Compeán, Oscar Loaiza-Brito, Aldo Martínez-Merino, Roberto Santos-Silva
2014 Physical Review D  
Finally from a K-theoretical perspective, we compute the presence of discrete RR charge of D-branes wrapping torsional cycles in a half-flat manifold.  ...  Then we can define a torsional differential operator d (T ) such that d (T ) σ p = 0 with d (T ) = d − κ : H p (Y 3 ; Z) −→ 0.

La Guerra contra las Drogas y la Cooperación internacional: el caso de Colombia

Jonathan D. Rosen, Roberto Zepeda Martínez
2016 Revista CS  
Este artículo analiza la política exterior de los Estados Unidos (EE.UU.) hacia Colombia con respecto al narcotráfico. El análisis se centra no solo en la Guerra contra las Drogas en Colombia sino también en los intereses de los EE.UU. en este país y en la región. La posición de Washington frente a este problema revela la política exterior de los EE.UU. hacia otros países en la región sobre el narcotráfico y el crimen organizado. Este trabajo analiza la cooperación entre los EE.UU. y Colombia

Black hole fusion in the extreme mass ratio limit

Roberto Emparan, Marina Martínez, Miguel Zilhão
2018 Physical Review D  
These can now be plugged back into (2.8) to solve for λðrÞ and λðθÞ as series expansions in 1=r and 1=ðθ − αÞ, respectively. Inverting these series, we find rðλÞ and θðλÞ.  ...  Instead, we will work in Hamiltonian formalism, with canonical momenta p μ ðλÞ in addition to the positions x μ ðλÞ. The equations were already derived in this manner in Ref. [10] .  ...  Clearly, this construction can be extended to all dimensions; simply replace the φ circles by spheres Ω D−3 .  ...
