Recently published book by Hikari: Order Relations for the Cryptanalysis of Substitution Ciphers on the Basis of Linguistic Data Structures as an Optimal Strategy by Norman Neukel

In order to analyze the solution behavior of general substitution ciphers for cryptanalysis, for the first time this book utilizes the methods of set optimization. The book investigates how to proceed optimally in a specific case. Linguistic data structures, such as the frequencies of the different letters, bigrams and trigrams, are divided into sets and described by order relations appropriate to the German and English languages. In the context of cryptanalysis this allows new solutions of existing models within the scope of set-valued order relations. This approach leads to an optimal strategy.

Recently published book by Hikari: Compensation Payments for Aircraft Noise in an Urban Building Conflict Situation on the Basis of a Set-Valued Conjugate Duality by Norman Neukel

This book investigates compensation payments to property owners for aircraft noise in urban conflict situations in the region surrounding the airport for the first time on the basis of a set-valued conjugate duality. This optimal perturbation approach serves as justification for the realization of variable results. This "dual" socio-economy indicates the action strategy of different interest groups. Linear point sets as a new optimum set varying according to socio-economic properties and a payment function are therefore well substantiated.
