Supremum and infimum of specific sets
Click For Summary
SUMMARY
The discussion focuses on determining the supremum and infimum of various mathematical sets defined by specific formulas involving natural and integer numbers. Set A has a supremum of +∞, while sets B, C, D, and E require careful analysis to find their bounds. For set D, the supremum is established as 0.6666... and the infimum is 0. Set E's supremum is determined to be 1, with an infimum of 0. The participants emphasize the importance of rigorous proof and understanding the definitions of supremum and infimum in the context of bounded and unbounded sets.
