“…Using the preceeding discussion, along with (1.2) and (1.3), we can write equation (1.1) as Le [33] proved the existence of a weak solution in a bounded domain for d = 1, 2, 3. The reader can refer to [3,29,34,42,47] and references within for some recent developments. The (deterministic) LLB equation turns out to be insufficient, for example, to capture the dispersion of individual trajectories at high temperatures.…”

We study the stochastic Landau-Lifshitz-Bloch equation perturbed by pure jump noise. In order to understand and also control the fluctuations and jumps observed in the hysteresis loop, we add noise and an external control to the effective field. We consider the control operator as one that can depend, even nonlinearly on both the control and the associated solution process. We reformulate the problem as a relaxed control problem by using random Young measures and show that the relaxed problem admits an optimal control. The proof employs the Aldous condition for establishing tightness of laws and a modified version of the Skorohod Theorem for obtaining subconvergence of laws.

“…After that, Li-Guo-Zeng [29] obtained the global existence of smooth solution in R 2 for any initial data, and in R 3 for small initial data. Recently, Ayouch-Benmouane-Essouf [1] established the uniqueness and local existence of the LLB equation in a bounded domain of R 3 . For the results of the stochastic LLB equation, see [5,20,26,34] and the references therein.…”

We focus on the existence and uniqueness of the three-dimensional Landau-Lifshitz-Bloch equation supplemented with the initial data in Besov space Ḃ 3 2 2,1 . Utilizing a new commutator estimate, we establish the local existence and uniqueness of strong solutions for any initial data in Ḃ 3 2 2,1 . When the initial data is small enough in Ḃ 3 22,1 , we obtain the global existence and uniqueness. Furthermore, we also establish a blow-up criterion of the solution to the Landau-Lifshitz-Bloch equation and then we prove the global existence of strong solutions in Sobolev space under a new condition based on the blow-up criterion.
