ABSTRACT

We show that $bu \wedge BO(n)$ splits as a wedge product of suspended copies of $HZ/2$, $bu$, and $bu \wedge BO(1)$ at prime 2 for $n = 2, 3,$ and 4. Similarly, we show that $bu \wedge BSO(2n + 1)$ splits as a wedge product of suspended copies of $HZ/2$ and $bu$ at prime 2 for $n = 1$ and 2.
