Outline of Final Research Achievements |
Let p be a prime number, B_p,∞ the cyclotomic Z_p-extension of the rational number field Q, B_p,n the n-th layer of B_p,∞/Q and h_p,n the class number of B_p,n. We obtained the following: Let p be a prime number which is not congruent to 1 or -1 modulo 16. Then the p-part of the class number h_p,m,n of B_2,mB_p,n is bounded as n tends to infinity for the fixed m. We can see the result in [④].
