We prove a continuous-time Carleson embedding theorem with constant for a system of square-integrable continuous martingales whose quadratic covariations mimic the generalised…

The optimal bound in a dyadic version of Uchiyama's Lemma
J. Fladung, S. Petermichl
The best known constant in Uchiyama's Lemma is . A conjecture states that this cannot be improved. We show that the constant also stands in a dyadic version of Uchiyama's Le…
