Tree Enumeration from the Incidence Matrix
International Journal of Electrical Engineering & Education, 1987Cyclic tree generation via the outer product of vectors in determinant evaluation by Grassmann's algebra yields an algorithm for symbolic circuit analysis with a particularly simple test applicable to the enumeration of symbolic terms in both numerator and denominator of transfer functions of active circuits.

Matrix projective spaces and twistorlike incidence structures
Journal of Mathematical Physics, 2009We consider projective spaces constructed over (real or complex) matrix rings and study their topological separation properties. The method of construction results in non-Hausdorff spaces, where incidence properties associated with a Grassmann/flag interpretation of the spaces are neatly encoded in the lack of standard topological separation properties.
