Classifying Quadratic Forms Over Z2 in Four Variables

Amrita Acharyya & Gerard Thompson · Journal of Advances in Mathematics and Computer Science · 2018

Quadratic forms in four variables over the field 2 are sorted first of all with respect to permutation symmetry. Thereafter it is shown that any such form is equivalent to one of seven such canonical forms. The orthogonal group of each one of these seven forms is obtained. The pa...
