-adic regulator
Let , , , , , and be as in the entry regulator, but with taken to be a CM field.
Define the -adic logarithm by
Let be the matrix with general entry given by . The absolute value of the determinant
of this matrix is again independent of your choice of basis for the units and of the ordering of the embeddings
. This value is called the -adic regulator of , and is denoted by , or .
