Fixed point theorems and convergence theorems for a generalized nonexpansive mapping in uniformly convex Banach spaces
Chang Il Rim, Jong Gyong Kim
In this paper, we prove the existence of fixed points of mappings satisfying the condition (Da), a kind of generalized nonexpansive mappings, on a weakly compact convex subset in a…
Existence and convergence theorems for monotone generalized alpa-nonexpansive mappings in uniformly convex partially ordered hyperbolic metric spaces and its application
Chang Il Rim, Jong Gyong Kim, Chol-Hui Yun
In this paper, we generalize the existence result in [14] and prove convergence theorems of the iterative scheme in [12, 16] for monotone generalized alpa-nonexpansive mappings in…
The Number of Irreducible Polynomials over Finite Fields of Characteristic 2 with Given Trace and Subtrace
Won-Ho Ri, Gum-Chol Myong, Ryul Kim +1
In this paper we obtained the formula for the number of irreducible polynomials with degree over finite fields of characteristic two with given trace and subtrace. This formula…
The Relation Between Diagrams of a Knot and Its Unknotting Number
Kang-Il Ri, Yun-Ho An, Chang-Il Rim
The unknotting number is the classical invariant of a knot. However, its determination is difficult in general. To obtain the unknotting number from definition one has to investiga…
