minor

Minor is used in two meanings

  • a submatrix of a matrix

  • the determinant of a square submatrix of a matrix with entries in a commutative ring

where the second meaning is a bit more standard. There is a noncommutative analogue, namely the quasiminor, which is the quasideterminant of a square submatrix of a matrix with entries in a noncommutative ring.
