Abstract |
|
Convex sets are discussed here in linear spaces over scalars other than the reals. To facilitate this development, the interval [0,1] is generalized to a unit interval in an arbitrary division ring. The interval [0,1] is shown to be the maximum generalized unit interval in the real number field, the complex number field, and the quaternion division ring. Several elementary theorems on convexity are proved for linear spaces over scalars having generalized unit intervals of certain types. |
