Title: The stochastic heat inclusion with fractional time derivative driven by time-space Brownian white noise

Abstract: We study a time-fractional stochastic heat inclusion driven by additive

time-space Brownian noise given by:

∂^α/∂t^α Y (t, x) ∈ λ∆Y (t, x) + G(t, x, Y (t, x)) + σW (t, x); (t, x) ∈ (0, ∞) × R^d.

Here d ∈ N = {1, 2, ...} is the space dimension, x ∈ R^d denotes a point in

space, t ≥ 0 denotes the time.

Here d ∈ N = {1, 2, ...} is the space dimension, x ∈ R^d denotes a point in

space, t ≥ 0 denotes the time. The fractional time derivative is interpreted as

the Caputo derivative of order α ∈ (0, 2). We show the following:

a) If a solution exists, then it is a fixed point of a specific set-valued map.

b) Conversely, any fixed point of this map is a solution of the heat inclusion.


This series of webinars addresses all interested people in probability, stochastic analysis, control, risk evaluation, statistics, with a view towards applications, in particular to finance, economy, energy markets and production, but also to physics and biology. This series brings together the major research themes of the group. STAR stands for STochastics And Risk! Welcome!
