    • Relative homotopy in relational structures 

      Witbooi, Peter (Cambridge University Press, 2018)
      The homotopy groups of a finite partially ordered set (poset) can be described entirely in the context of posets, as shown in a paper by B. Larose and C. Tardif. In this paper we describe the relative version of such a ...

    • A robust spectral method for pricing of American put options on zero-coupon bonds 

      Pindza, Edson; Patidar, Kailash C. (Global-Science Press, 2018)
      American put options on a zero-coupon bond problem is reformulated as a linear complementarity problem of the option value and approximated by a nonlinear partial differential equation. The equation is solved by an ...

    • Some meta-cayley graphs on dihedral groups 

      Allie, Imran; Mwambene, Eric (Springer, 2019)
      In this paper, we define meta-Cayley graphs on dihedral groups. We fully determine the automorphism groups of the constructed graphs in question. Further, we prove that some of the graphs that we have constructed do not ...
