What do you mean by Consumption Set?

Consumption Set:

We notice a consumer faced along with possible consumption bundles within consumption set X. We generally assume that X is the nonnegative orthant into R^L as demonstrated in the right figure, but more exact consumption sets may be utilized. For illustration, it may permit consumptions of some good into a suitable interval such like leisure as demonstrated in the left figure, or we might only comprise bundles which would provide the consumer at least a subsistence existence or which includes only integer units of consumptions as demonstrated in figure. We suppose that X is a closed and convex set unless otherwise stated. There convexity of a consumption set implies that each good is divisible and can be consumed through fraction units.

The left figure: A consumption set which reflects legal limit onto the number of working hours. The right figure: the consumption set R²₊
