A stochastic card balance management problem with continuous and batch-type bilateral transactions

open access: yesOperations Research Perspectives, 2023
We study a stochastic continuous-review card balance management problem with two transaction patterns, namely, continuous and batch-type bilateral transactions, both in a Markovian environment.

On the relations between increasing functions associated with two-parameter continuous martingales

open access: yesStochastic Processes and their Applications, 1990
Let \((\Omega,{\mathcal F},P,({\mathcal F}_ z)_{z\in T})\), \(T=[0,1]^ 2\), be a stochastic two-parameter basis satisfying the usual (F1)-(F4) conditions of Cairoli and Walsh. Let also M be a two-parameter continuous martingale bounded in \(L^ 2\) and null on the axes. Then \(M^ 2\) has the following Doob-Meyer decomposition: \[ M^ 2_{st}=2\int^{s}_{0}\

Local Time for Two-Parameter Continuous Martingales with Respect to the Quadratic Variation

open access: yesThe Annals of Probability, 1988
The author studies the local time for two-parameter continuous martingales M as a density of the ``measure of sojourn time'' with respect to the quadratic variation \(\). First she shows that there exists a process \(\{L(x,s,t);\) \(x\in {\mathbb{R}}\setminus \{0\},\) \((s,t)\in {\mathbb{R}}^ 2_+\}\) satisfying the occupation density formula and which ...
