    • A schauder fixed point theorem in semilinear spaces and applications 

      Agarwal, Ravi P; Arshad, Sadia; O’Regan, Donal; Lupulescu, Vasile (Springer Nature, 2013-01-01)
      In this paper we present existence and uniqueness results for a class of fuzzy fractional integral equations. To prove the existence result, we give a variant of the Schauder fixed point theorem in semilinear Banach spaces.
    • Fixed-point theory for weakly sequentially continuous mappings 

      O'regan, D. (Elsevier BV, 1998-03-01)
      Some fixed-point theorems are established for weakly contractive operators. These results will then be used to establish existence principles for functional, differential, and integral equations.
    • The magnetotelluric phase tensor 

      Caldwell, T. Grant; Bibby, Hugh M.; Brown, Colin (Oxford University Press (OUP), 2004-08-01)
      The phase relationships contained in the magnetotelluric (MT) impedance tensor are shown to be a second-rank tensor. This tensor expresses how the phase relationships change with polarization in the general case where the ...
