Local independence of fractional Brownian motion
Ilkka Norros, Eero Saksman
Let S(t,t') be the sigma-algebra generated by the differences X(s)-X(s) with s,s' in the interval(t,t'), where (X_t) is the fractional Brownian motion process with Hurst index H be…
On the connected component of compact composition operators on the Hardy space
Eva A. Gallardo-Gutiérrez, Maria J. González, Pekka Nieminen +1
We show that there exist non-compact composition operators in the connected component of the compact ones on the classical Hardy space on the unit disc. This answers a questi…
On singular integral and martingale transforms
S. Geiss, S. Montgomery-Smith, E. Saksman
Linear equivalences of norms of vector-valued singular integral operators and vector-valued martingale transforms are studied. In particular, it is shown that the UMD(p)-constant o…
Pointwise characterizations of Hardy-Sobolev functions
Pekka Koskela, Eero Saksman
We establish simple pointwise characterizations of functions in the Hardy-Sobolev spaces within the range n/(n+1)<p <=1. In addition, classical Hardy inequalities are extended to t…
On certain sums over ordinates of zeta zeros
Aleksandar Ivić
Let denote imaginary parts of complex zeros of the Riemann zeta-function . Certain sums over the 's are evaluated, by using the function and…
