  • Bounding the Range of a Sum of Multivariate Rational Functions 
    Adm, Mohammad; Garloff, Juergen; Titi, Jihad; Elgayar, Ali (Springer, 2022)
    Bounding the range of a sum of rational functions is an important task if, e.g., the global polynomial sum of ratios problem is solved by a branch and bound algorithm. In this paper, bounding methods are discussed which ...
  • Bounding the Range of a Sum of Multivariate Rational Functions 
    Adm, Mohammad; Titi, Jihad; Elgayar, Ali; Garloff, Jürgen (in M. Ceberio and V. Kreinovich (eds.), Decision Making under Uncertainty and Constraints, Studies in Systems, Decision and Control 217, Springer Nature, 2023)
    Bounding the range of a sum of rational functions is an important task if, e.g., the global polynomial sum of ratios problem is solved by a branch and bound algorithm. In this paper, bounding methods are discussed which ...
  • A Survey of Classes of Matrices Possessing the Interval Property and Related Properties 
    Adm, Mohammad; Garloff, Juergen; Titi, Jihad (Reliable Computing, 2016)
    This paper considers intervals of real matrices with respect to partial orders and the problem to infer from some exposed matrices lying on the boundary of such an interval that all real matrices taken from the interval ...
  • Total Nonnegativity of Matrices Related to Polynomial Roots and Poles of Rational Functions 
    Adm, Mohammad; Garloff, Juergen; Titi, Jihad (Journal of Mathematical Analysis and Applications, 2016)
    In this paper totally nonnegative (positive) matrices are considered which are matrices having all their minors nonnegative (positive); the almost totally positive matrices form a class between the totally nonnegative ...
