Sparse Bounds for Rough Fourier Integral Operators
Wellars Banzi, Froduald Minani, Solange Mukeshimana +1
We prove pointwise bounds for rough Fourier integral operators by the Hardy-Littlewood maximal function. We assume the Fourier integral operators have amplitudes in $L^\infty…

Some More Sparse Bounds for Rough and Smooth Pseudodifferential Operators
Solange Mukeshimana, David Rule
Beltran \& Cladek~\cite{BC} use to bounds to prove sparse form bounds for pseudodifferential operators with Hörmander symbols in up to, but not including, t…

On Chaplygin models in f(G) gravity
Fidele Twagirayezu, Abraham Ayirwanda, Albert Munyeshyaka +3
The current work treats cosmological perturbation in a mixture of standard matter, Chaplygin gas as well as Gauss-bonnet fluids using a 1+3 covariant approach in the context of mod…
