Abstract: |
The intermediate value theorem has been generalized by the point of view of mapping and then use it to generalize Li-York theorem to several variables case and give bounded below character of composition operator on Bloch space in Cn unit ball. |
Key words: intermediate value theorem Darboux theorem Li-York theorem composition operator boundness below |
