A number of writers have defined a concept of angle in a normed linear space or metric space by means of the law of cosines, and have studied the properties of these angles obtaining, in some cases, characterizations of real inner product spaces. (For a summary of earlier results see MARTIN and VAL

We present an analogue of Uhlhorn's version of Wigner's theorem on symmetry transformations for the case of indefinite inner product spaces. This significantly generalizes a result of Van den Broek. The proof is based on our main theorem, which describes the form of all bijective transformations on
This paper mainly deals with a new kind of fuzzy relation equations based on inner transformation First, the inner projection of a fuzzy relation and the tuner transformation by a fuzzy relation are introduced, and also what is a fuzzy relation equation based on inner transformation ~s described Sec
