On Ground Fields of Arithmetic Hyperbolic Reflection Groups. II
Using authors's methods of 1980Using authors's methods of , 1981, some explicit finite sets of number fields containing all ground fields of arithmetic hyperbolic reflection groups in dimension at least 3 are defined, and explicit bounds of their degrees (over Q) are obtained.Thus, now, explicit bound of degree of ground …
