Hello,
I can't wrap my mind around this:
inf∅= ∞
sup∅= - ∞
Thank you in advance.

The infimum of the empty set is undefined. This is because the infimum is defined as the greatest lower bound of a set, but since the empty set has no elements, there is no lower bound to compare to.
No, the infimum of the empty set is not equal to zero. As mentioned before, the infimum of the empty set is undefined because there is no lower bound to compare to.
The supremum of the empty set is also undefined for the same reason as the infimum. The supremum is defined as the least upper bound of a set, but the empty set has no elements to compare to.
No, the infimum and supremum of the empty set cannot be any real number. As stated before, they are both undefined because there are no elements to compare to in the empty set. Therefore, they cannot be assigned any value.
Understanding the infimum and supremum of the empty set is important in mathematical analysis and set theory. It helps in defining the concepts of lower and upper bounds and understanding the behavior of sets with no elements. It also aids in proving theorems and solving problems related to sets and their properties.
