law of diminishing returns
The further the Isoquant is from the origin, the greater will be the level of output (i.e a higher isoquant represent a higher level of output) Two Isoquants can never intersect each other Isoquants always slopes downward
ridge lines is the combination of isoquants
producers equilibrium is achieved with isoquants and isocost curves
Ridge lines is a concept in Micro Economics related to Isoquants (which shows different combination of inputs for the same level of output). However, after a certain point Isoquant begins to slope upward, if there are 2 or more isoquants then there would be similar points on the other isoquants too... on joining these points, you get the ridge lines. Note: the point from where Isoquant slopes upward is a point where the marginal product of one of the input is negative.
a polygon is convex
A non convex is a concave and a convex is differently shaped
projector have concave or convex
the union of two convex sets need not be a convex set.
