報(bào)告摘要:
In this talk, wegive a detailed study of long-time dynamics generatedby the wave equation with time-dependent speed of propagation and time-dependent memory kernel. Within the novel theory of process on time-dependent spaces and the correct mathematical setting of memory kernel, we firstestablish the global well-posedness result in extended time-dependent memoryspace. Under the exponential decay control, we develop furthersome new time-space (energy) estimates to overcome the mixed difficulties fromtime-dependent speed of propagation and memory kernel, then obtain the dissipativity and regularity of the dynamicalprocess. In this work, we further study the existence and regularity of the time-dependent global attractor.
歡迎廣大師生參加!
