On the path structure of a semimartingale arising from monotone probability theory

Alexander C. R. Belton

Let $X$ be the unique normal martingale such that $X_{0} = 0$ and \[\mathrm{d}[X]_t=(1-t-X_{t-}) \mathrm{d}X_t+\mathrm{d}t\] and let $Y_{t} := X_{t} + t$ for all $t \geq 0$ ; the semimartingale…

Approximation via toy Fock space - the vacuum-adapted viewpoint

Alexander C. R. Belton

After a review of how Boson Fock space (of arbitrary multiplicity) may be approximated by a countable Hilbert-space tensor product (known as toy Fock space) it is shown that vacuum…
