Two-parameter Lévy processes: ItÔ formula, semigroups, and generators
We consider random Lévy fields, i.e., stationary fields continuous in probability and having independent increments. We prove that the trajectories of such fields have at most one jump on every line parallel to the axes. We derive an expression for the ItÔ change of variables for Lévy fields. We als...

| description | We consider random Lévy fields, i.e., stationary fields continuous in probability and having independent increments. We prove that the trajectories of such fields have at most one jump on every line parallel to the axes. We derive an expression for the ItÔ change of variables for Lévy fields. We also consider semigroups generated by Lévy fields and their generators. |

Доведено, що траєкторії такого поля мають не більше одного стрибка на кожній прямій, паралельній осям. Виведено формулу заміни змінних Іто дня полів Леві. Розгляную півгрупи, породжені полями Леві, і а інфінітезімальні оператори цих рун.
