Large-time asymptotics of the wave fronts length I The Euclidean disk

In a previous work, the second author gives a formula showing thatthe wave frontissued of a point of the unit disk hasa large time linear asymptotics. In the present paper, we give ashorter proofand compute the oscillating corrections.
