The notion of strongly Lie zero-product preserving maps on normed algebras as a generalization of Lie zero-product preserving maps are dened. We give a necessary and sufficient condition from which a linear map between normed algebras to be strongly Lie zero-product preserving. Also some hereditary properties of strongly Lie zero-product preserving maps are presented. Finally the second dual of...

Product-line dynamics arise from shocks to preference heterogeneity. For example, in the potato chip category I study, consumer concerns over fat levels in foods created two desirable alternatives (low fat and zero fat) for ea...
