bilinear (not comparable)

1. (linear algebra, of a function in two variables) Linear (preserving linear combinations) in each variable.

   The function ${\displaystyle f(x,y)=xy}$ is bilinear, because ${\displaystyle f(ax+bu,y)=af(x,y)+bf(u,y)}$ and ${\displaystyle f(x,ay+bv)=af(x,y)+bf(x,v)}$ for all values.

2. (complex analysis, physics, engineering) Of or pertaining to a Möbius transformation (type of conformal map representable as the ratio of two linear functions).
