A semipolynomial parameterization of fourth-order spinor groups (Q600740)

For nonnegative integers \(p\) and \(q\) with \(p+q=4\), the author studies the spinor group \(\text{Spin}_{+}(p,q)\) containing the even elements of the Clifford algebra \(\mathcal{C}l(p,q)\). He obtains a representation of the elements of this spinor group in terms of an exterior exponential.
