Periodic oscillations in the restricted Hip-Hop 2N+1 body problem
Andres Rivera, Oscar Perdomo, Nelson Castaneda
We prove the existence of periodic solutions of the restricted -body problem when the -primaries move on a periodic Hip-Hop solution and the massless body moves on the…
Periodic oscillations in a 2N-body problem
Oscar Perdomo, Andrés Rivera, John A. Arredondo +1
Hip-Hop solutions of the -body problem are solutions that satisfy at every instance of time, that the bodies with the same mass , are at the vertices of two regular …
Preparation of 3-qubit states
Oscar Perdomo, Nelson Castaneda, Roger Vogeler
We will call a pure qubit state real if all its amplitudes are real numbers. We show that any real 3-qubit state can be prepared using gates and at most four controlled-$Z…
Path coverings with prescribed ends in faulty hypercubes
Nelson Castañeda, Ivan S. Gotchev
We discuss the existence of vertex disjoint path coverings with prescribed ends for the -dimensional hypercube with or without deleted vertices. Depending on the type of the set…
