• Gronwall–Bellman estimates for linear Volterra-type inequalities with delay 

  Buedo Fernández, Sebastián; Rodríguez López, Rosana (University of Szeged, 2018-10-01)

  We obtain some estimates of Gronwall–Bellman-type for Volterra’s inequalities, which have applications to the study of the stability properties of the solutions to some linear functional differential equations.

• On the stability properties of a delay differential neoclassical model of economic growth 

  Buedo Fernández, Sebastián; Liz Marzán, Eduardo (University of Szeged, 2018-06-26)

  The main aim of this paper is to establish sharp global stability conditions for the positive equilibrium of a well-known model of economic growth when a delay is considered in the production function. In order to deal ...

• Optimization method for identifying the source term in an inverse wave equation 

  Deiveegan, Arumugam; Prakash, Periasamy; Nieto, Juan J (Texas State University, 2017)

  In this work, we investigate the inverse problem of identifying a space-wise dependent source term of wave equation from the measurement on the boundary. On the basis of the optimal control framework, the inverse problem ...

• Positive solutions for second-order boundary-value problems with sign changing Green's functions 

  Cabada, Alberto; Enguiça, Ricardo; López Somoza, Lucía (Texas State University, 2017)

  In this article we analyze some possibilities of finding positive solutions for second-order boundary-value problems with the Dirichlet and periodic boundary conditions, for which the corresponding Green's functions change ...

• Constant sign solution for a simply supported beam equation 

  Cabada, Alberto; Saavedra, Lorena (University of Szeged, 2017)

  The aim of this paper is to ensure the existence of constant sign solutions for the fourth order boundary value problem. This problem models the behavior of a suspension bridge assuming that the vertical displacement ...
