A note on formal periods

  title={A note on formal periods},
  author={Fritz Hormann},
We give an elementary description of the space of formal periods of a mixed motive. This allows for a simplified reformulation of the period conjectures of Grothendieck and Kontsevich-Zagier. Furthermore, we develop a machinery which in principle allows to determine the space of formal periods for an arbitrary mixed motive explicitly. 


Galois theory of periods
In this mostly expository note we explain how Nori's theory of motives achieves the aim of establishing a Galois theory of periods, at least under the period conjecture. We explain and compareExpand
Some remarks concerning the Grothendieck Period Conjecture
We discuss various results and questions around the Grothendieck period conjecture, which is a counterpart, concerning the de Rham-Betti realization of algebraic varieties over number fields, of theExpand
Periods and the conjectures of Grothendieck and Kontsevich – Zagier
This paper concerns a class of complex numbers, called periods, that appear naturally when comparing two cohomology theories for algebraic varieties (the first defined topologically and the secondExpand
Transcendence and linear relations of $1$-periods.
We study three fundamental questions about $1$-periods and give complete answers. 1) We give a necessary and sufficient for a period integral to be transcendental. 2) We give a qualitativeExpand
