  • Zero sum sign-central matrices and applications 
    Barragan, Luis A.; Dahl, Geir; Dominguez, Alberto; Otin, Arantxa (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    A matrix with a nonzero nonnegative vector in its null space is called central . We study classes of central matrices having zero column sums. The study is motivated by an engineering application concerning induction ...
  • A Zero-Coupon Bond based Spread Option : An Application of the Heath-Jarrow-Morton ModelRestricted Access 
    Skåre, Kjersti Rekdal (Master thesis / Masteroppgave, 2013)
    In this thesis we derive the price of a spread option based on two zero-coupon bonds. The two bonds will represent di erent nancial markets, and the HJM framework is used as the model for the underlying forward rates. We ...
  • Zero-one completely positive matrices and the A(R, S) classes 
    Dahl, Geir; Haufmann, Torkel Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    A matrix of the form A = BBT where B is nonnegative is called completely positive (CP). Berman and Xu (2005) investigated a subclass of CP-matrices, called f0, 1g-completely positive matrices. We introduce a related concept ...

    Väänänen, Jouko (Research report / Forskningsrapport, 1978)
