Podio-Guidugli and the present authors; the nonlocal model here studied consists of a highly nonlinear parabolic equation coupled to an ordinary differential inclusion of subdifferential type. The inclusion originates from a free energy containing the indicator function of the interval in which the order parameter of the phase segregation attains its values. It also contains a nonlocal term modeling long-range interactions. Due to the strong nonlinear couplings between the state variables (which even involve products with time derivatives), the analysis of the state system is difficult. In addition, the presence of the differential inclusion is the reason that standard arguments of optimal control theory cannot be applied to guarantee the existence of Lagrange multipliers. In this paper, we employ recent results proved for smooth logarithmic potentials and perform a so-called `deep quench' approximation to establish existence and first-order necessary optimality conditions for the nonsmooth case of the double obstacle potential. ]]> Pierluigi Colli, Gianni Gilardi and Jürgen Sprekels Wed, 1 Mar 2017 08:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13447 Indirect stabilization of hyperbolic systems through resolvent estimates http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13447 indirect stabilization). The energy estimate is achieved by means of suitable estimates of the resolvent operator norm. We apply this technique to a wave-wave system and to a wave-Petrovsky system. ]]> Roberto Guglielmi Wed, 1 Mar 2017 08:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13448 Identification problems of retarded differential systems in Hilbert spaces http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13448 Jin-Mun Jeong and Seong-Ho Cho Wed, 1 Mar 2017 08:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13449 Sufficiency and mixed type duality for multiobjective variational control problems involving $\alpha$-V-univexity http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13449 Sarita Sharma, Anurag Jayswal and Sarita Choudhury Wed, 1 Mar 2017 08:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13450 On an inverse problem for fractional evolution equation http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13450 Nguyen Huy Tuan, Mokhtar Kirane, Long Dinh Le and Van Thinh Nguyen Wed, 1 Mar 2017 08:00:00 GMT http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13451 The analyticity and exponential decay of a Stokes-wave coupling system with viscoelastic damping in the variational framework http://www.aimsciences.org/test_aims/journals/displayPaper.jsp?paperID=13451 Jing Zhang Wed, 1 Mar 2017 08:00:00 GMT
