It was introduced fifteen years ago in the speaker’s book on motives, in the context of Grothendieck’s period conjecture. Another interesting context is that of (arithmetic) connections, where V, V’ are solution spaces at two k-, k’-rational points, and iota is parallel transport along a path.
We shall discuss this category, and outline these two contexts and their intersection, with a view toward transcendental number theory. |
