I came across some behavior with matrix multiplication that doesn't seem very intuitive to me.
N=matrix(QQ,[[1,1],[0,1]]) T=matrix(GF(7),[[1,1],[0,1]]) L=N*T L,L.parent() produces ([0 0] [0 0], Full MatrixSpace of 2 by 2 dense matrices over Ring of integers modulo 1) I tried to search for the expected behavior with little success. So, I used as a model GF(7) times QQ: GF(7)(2)*QQ(1) which produces an error: TypeError: unsupported operand parent(s) for '*': 'Finite Field of size 7' and 'Rational Field' Is this coercion to Zmod(1) with matrices the expected behavior? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
