【Abstract】 We give an algorithm to determine whether {a₁,...,a_n}π₁（T） can be geometrically realizeb by Heegaard curves on T in a finite nimber of steps by using Chillingworth’s methods （[1] and [2]）,where T denotes an orientable closed surface with genus n>1,and we describe an algeebraic characteristic for homology lens spaces.更多还原
