Kurihara's determinant conjecture for minus theta-kernel bases
Kurihara's determinant conjecture for minus theta-kernel bases
Let be a finite abelian CM-extension, let be an odd prime, and put . Let be the theta-kernel module, let be the map defined in the source for an intermediate CM-field of , and let be the corresponding equivariant -value. Kurihara's determinant conjecture. There is a basis of over such that, after defining by restriction to every intermediate CM-field , for every such and every subset with , the determinant of with respect to the induced bases satisfies
The source attributes this formulation to Kurihara and uses it to relate determinant and Fitting-ideal formulations of the minus eTNC; no resolution is given in the supplied text.
