A.1 Convex Sets

Let b1-math-0001 and b1-math-0002 be two different points in b1-math-0003. The line crossing b1-math-0004 and b1-math-0005 is given by the set of points b1-math-0006 of the form b1-math-0007, where b1-math-0008 ranges all the values in b1-math-0009. In turn, the segment between b1-math-0010 and b1-math-0011 is the set of points b1-math-0012, where is now restricted to be .

A set is said ...
