Abstract:

Using  methods of family and construction, we gave a new definition of stronger sensitivitythickly syndetic sensitivity,  proved that a minimal weakly mixing system or nonminimal Msystem is thickly syndetically sensitive. Also, we constructed a system which is syndetically sensitive but not thickly sensitive and thickly syndetically sensitive.

Key words: thick sensitivity, syndetic sensitivity, thickly syndetic sensitivity
