Equivalently, they can be algebraically defined as biparacomplex or complex product manifolds, i.e., manifolds endowed with three tensor fields of type $(1,1)$, $F$, $P$ and $J=F \circ P$, where the two first are product and the third one is complex, and they mutually anti-commute. In this case, it is well known that there exists a unique torsion-free connection parallelizing the structure. In the present paper, we study connections attached to non-integrable almost biparacomplex manifolds.sections 3 and 4 rewritten and simplified, added subsection 4.1 and updated referencesDifferential Geometry53A55, 53A60, 53B05, 53C10Connections functorially attached to almost complex product structurestext
