Homotopy of representations up to homotopy
Olivier Brahic, Pedro Frejlich
The paper defines morphisms between representations up to homotopy of Lie algebroids and shows that their cohomology behaves functorially, preserving homotopy invariance and local…

Concurring reduction schemes for Dirac structures
Dan Aguero, Alessandro Arsie, Pedro Frejlich +1
The notion of \emph{concurrence} was recently proposed as the natural compatibility relation between Dirac structures, generalizing the commutativity of two Poisson structures. We…

Dirac products and concurring Dirac structures
Pedro Frejlich, David MartÃnez Torres
We discuss in this note two dual canonical operations on Dirac structures and -- the \emph{tangent product} and the \emph{cotangent product} .…
