Oscillatory singularities in Bianchi models with magnetic fields
Stefan Liebscher, Alan D. Rendall, Sophonie Blaise Tchapnda
An idea which has been around in general relativity for more than forty years is that in the approach to a big bang singularity solutions of the Einstein equations can be approxima…
Hankel operators on holomorphic Hardy-Orlicz spaces
Benoit F. Sehba, Edgar Tchoundja
We characterize the symbols of Hankel operators that ex- tend into bounded operators from the Hardy-Orlicz into in the unit ball of…
Quantum associative memory with improved distributed queries
J. -P. Tchapet Njafa, S. G. Nana Engo, Paul Woafo
The paper proposes an improved quantum associative algorithm with distributed query based on model proposed by Ezhov et al. We introduce two modifications of the query that optimiz…
On the spherically symmetric Einstein-Yang-Mills-Higgs equations in Bondi coordinates
Calvin Tadmon, Sophonie Blaise Tchapnda
We revisit and generalize, to the Einstein-Yang-Mills-Higgs system, previous results of D. Christodoulou and D. Chae concerning global solutions for the Einstein-scalar field and t…
