Title: Possible numbers of nonzero entries in a matrix with a given term rank
Abstract:The possible numbers of nonzero entries in a matrix with a given term rank aredetermined respectively in the generic case, the symmetric case and the symmetric case with 0’s on the main diagonal. The ...The possible numbers of nonzero entries in a matrix with a given term rank aredetermined respectively in the generic case, the symmetric case and the symmetric case with 0’s on the main diagonal. The matrices that attain the largest number of nonzero entries are also determined.Read More
