A Note on Time-reversibility of Multivariate Linear Processes
We solve an important open problem by deriving some readily verifiable necessary and sufficient conditions for a multivariate non-Gaussian linear process to be time-reversible, under two sets of regularity conditions on the contemporaneous dependence structure of the innovations. One set of regularity conditions concerns the case of independent-component innovations, in which case a multivariat...

15 صفحه اولNote on Radial Dunkl Processes
This note encloses relatively short proofs of the following known results: the radial Dunkl process associated with a reduced system and a strictly positive multiplicity function is the unique strong solution for all time t of a stochastic differential equation of a singular drift (see [12] for the original proof and [4] for a proof under additional restrictions), the first hitting time of the ...
متن کاملA note on linear discrepancy
Close upper and lower bounds on the linear discrepancy of incidence matrices of directed graphs are determined. For such matrices this improves on a bound found in the work of Doerr [Linear discrepancy of basic totally unimodular matrices, The Electronic Journal of Combinatorics, 7:Research Paper 48, 4 pp., 2000].
متن کاملA Note on Linear Functionals
A slight modification of the example given shows that if N is chosen arbitrarily, there exists a limited region* having at least JV distinct points O whose conjugates D lie at infinity.f Theorem III becomes false if in the hypothesis the region R is not assumed limited, for the reader may verify that no point O of the region R has its conjugate at infinity if R is the entire plane slit along th...
