Stochastic integration and stochastic PDEs driven by jumps on the dual of a nuclear space

Abstract: We develop a novel theory of weak and strong stochastic integration for cylindrical martingalevalued measures taking values in the dual of a nuclear space. This is applied to develop a theory of SPDEs with rather general coefficients. In particular, we can then study SPDEs driven by general Lévy processes in this context.

“…We hope that with our work more applications will appear. Second, in [15] a new theory of stochastic integration and stochastic PDE's in Φ ′ β driven by Lévy noise has been introduced. Much of the work on this article is motivated to show convergence of solutions of these stochastic PDE's.…”

“…Remark 4.2. Since the Hilbert space H is separable, it follows from Definition 4.1(2), and from Proposition 3.8 in Fonseca-Mora (2018), that for each g ∈ G, the map (r, ω, u) → q r,u (Φ(r, ω, u) * g) 2 is P T ⊗ B(U )/B(R + )-measurable. Therefore, because G is a separable Hilbert space, the map (r, ω, u) → ||Φ(r, ω, u)|| 2 L 2 (Hq r,u ,G) is P T ⊗ B(U )/B(R + )-measurable and the integrand in (4.1) is well-defined.…”

“…The concept of cylindrical martingale-valued measures in a locally convex space was introduced in the work Fonseca-Mora (2018), and generalizes to locally convex spaces the martingale-valued measures introduced for the finite dimensional setting by Walsh (1986) and then extended to infinite dimensional settings such as Hilbert spaces (Applebaum, 2006) and duals of nuclear Fréchet spaces (Xie, 2001). However, in this work we will consider such objects only in the Hilbert space setting.…”

“…[5,6,23,53]). However, in recent years there has been an increasing interest in the usage of other classes of cylindrical semimartingales as such driving noise; we can cite, for example, the cylindrical Lévy processes [21,26,28,38,43], cylindrical martingalevalued measures [13] and cylindrical continuous local martingales [33,34,54]. To the extent of our knowledge, none of these works considers stochastic integration with respect to general cylindrical semimartingales in a general locally convex space.…”
