For a common emitter configuration, if $$\alpha $$ and $$\beta $$ have their usual meanings, the incorrect relationship between $$\alpha $$ and $$\beta $$ is :

$$\alpha = {\beta \over {1 + \beta }}$$

$$\alpha = {{{\beta ^2}} \over {1 + {\beta ^2}}}$$

$${1 \over \alpha } = {1 \over \beta } + 1$$

$$\alpha = {\beta \over {1 - {\beta ^2}}}$$
