Quasi-concave function
In that Analysis one is called Function f of one Interval I (or more generally one convex subset C one real Vector space ) after convex ,if for all x ,y out I (and/or.out C ) and t between 0 and 1applies:
A function is called quasi-concave ,if for all the quantity is convex.
Everyone concave function is quasi concave,however is for example those Gauss bath tub curve over only quasi-concave,not however concave.
