A simple recurrence formula for the number of rooted maps on surfaces by edges and genus [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
We establish a simple recurrence formula for the number $Q_g^n$ of rooted orientable maps counted by edges and genus. The formula is a consequence of the KP equation for the generating function of bipartite maps, coupled with a Tutte equation, and it was

On Matrix‐Based Cryptography Using Matrix Norm and Special Integer Sequences

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT In this paper, a novel matrix‐based encryption approach based on the Affine Hill cipher is presented. The key matrix is constructed using the Narayana integer sequence, and the Frobenius norm of the key matrix is used as a scaling factor in the key construction.

Renormalization techniques for inflation systems and some of their applications

open access: yesActa Crystallographica Section A, EarlyView.
In this work, renormalization methods for quantities related to the diffraction of inflation systems are surveyed.Exact renormalization techniques are important and powerful, particularly for inflation‐generated systems. We review recent results in this direction.

Continuous dependence and differentiation of solutions of finite difference equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
Conditions are given for the continuity and differentiability of solutions of initial value problems and boundary value problems for the nth order finite difference equation, u(m+n)=f(m,u(m),u(m+1),…,u(m+n−1)),m∈ℤ.

Entrepreneurial State as a Creative Destroyer: Comparison of Hong Kong and Singapore's Creative Industries

open access: yesCreativity and Innovation Management, EarlyView.
ABSTRACT This paper explores the limits of mission‐directed entrepreneurial states by drawing on the theory of recombinant innovation and F.A. Hayek's insights on the spontaneous growth of knowledge in society. First, the use of discretionary policymaking curtails the range of knowledge generated in the process of social interaction, limiting the scope
