我们分类,同构,椭圆曲面的不规则性,有一个奇异的纤维(必然类型I6 *)。它们都是椭圆模曲面(Shioda [11]),所以这个问题间接等价于SL ~ 2(Z)的某些子群的分类.这些曲面然后被用来产生具有最大Picard数的(椭圆)曲面的例子,其中q =1,anypg≥1(对于eq =0的情况,参见Escherson [7])。最后,分类产生了超几何函数,θ函数和某些自守形式之间的一些有趣的关系。
We classify, up to isomorphism, elliptic surfaces with irregularity one having exactly one singular fiber (necessarily of typeI6*). All of them turn out to be elliptic modular surfaces (Shioda [11]), so that the problem is indirectly equivalent to classifying certain subgroups ofSL2(Z). These surfaces are then used to produce examples of (elliptic) surfaces withq=1, anypg≥1, which have maximal Picard number (see Persson [7] for the caseq=0). Finally, the classification yields some interesting relationships between hypergeometric functions, theta functions, and certain automorphic forms.
