Reaction-Diffusion Equations with Spatially Distributed Hysteresis

Abstract: We study systems of reaction-diffusion equations with discontinuous spatially distributed hysteresis in the right-hand side. The input of hysteresis is given by a vector-valued function of space and time. Such systems describe hysteretic interaction of non-diffusive (bacteria, cells, etc.) and diffusive (nutrient, proteins, etc.) substances leading to formation of spatial patterns. We provide sufficient conditions under which the problem is well posed in spite of the discontinuity of hysteresis. These conditio… Show more

“…The reaction-diffusion equations with hysteresis have been considerably studied during the last decades (see [18,19,11,[20][21][22]14,23] and references therein). In particular, some research have been done on the hysteretic reaction-diffusion equations coming from biochemistry, see Section 5.5 of [5] and [18,19,24,6,25].…”

“…In particular, some research have been done on the hysteretic reaction-diffusion equations coming from biochemistry, see Section 5.5 of [5] and [18,19,24,6,25]. It is remarked that P. Gurevich et al [20,21] studied the reaction-diffusion equations involving a hysteretic discontinuity in the source term, which is defined at each spatial point. They mainly discussed the existence and uniqueness of solutions as well as their continuous dependence on initial data for a wide class of initial data.…”

“…Differential equations with non-ideal relays have been previously used to model reaction and diffusion processes in spatially distributed colonies of bacteria [21,22,38,19]. In contrast to our setting, all relays in these models have been assumed identical (that is, having the same bi-stability range), while spatial patterns appeared, in particular, due to the spatial diffusion of environmental substances.…”

“…How would the solutions behave if the hysteresis operator converged to a non-ideal relay (i.e., the functions ψ 1 and ψ 2 approached step functions)? In order to resolve the above questions we might refer Gurevich and Tikhomirov [19], where parabolic problems with non-ideal relay are treated. …”
