linear space

   <mathematics> A {vector space} where all {linear combinations}
   of elements are also elements of the space.  This is easy for
   spaces of numbers but not for a space of functions.  Roughly,
   this is to say that multiplication by numbers, and addition of
   elements is defined in the space.
