WebWhen the medium lacks inversion symmetry, the excursions in the positive direction differ from those in the negative direction. The response is not symmetric: the zero crossings are not symmetrically placed, and the … WebThe notion of general quasi-overlaps on bounded lattices was introduced as a special class of symmetric n-dimensional aggregation functions on bounded lattices satisfying some bound conditions and which do not need to be continuous. In this paper, we continue developing this topic, this time focusing on another generalization, called general pseudo …
