The notion can be described more conceptually with the function field.

The function field is then the set of all meromorphic functions on the variety.

In any case, the meromorphic functions form a field, the function field.

This point of view is developed further in function field (scheme theory).

This is also the function field of the projective line.

To any irreducible algebraic variety is associated its function field.

A 7-bit function field follows, which is used in conjunction with the opcode to specify an operation.

More general fields, such as function fields over the complex numbers.

Nonetheless, function fields often serves as a source of intuition what should be expected in the number field case.

In other words, it depends only on the function field of the variety.
