Right-angled Artin subgroups of mapping class groups of finite-type orientable surfaces have been studied from diverse perspectives. The discovery of these subgroups implies, indirectly, certain constraints on the existence of other subgroups. This talk aims to demonstrate that small powers of Dehn twists generate a right-angled Artin group when their associated simple closed curves exhibit intersection number 0 and N where N is uniformly given.
