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.
