  In this thesis, we investigated some properties of (left)near fields and
derived some results. We are focusing on $D(\alpha, \beta)$ which is the
generalized set of distributive elements of a nearfield. In particular, we
investigated some conditions on $\alpha,\beta, \alpha+\beta$ for $D(\alpha,
\beta)$ to be a subfield of $\mathbb{F}_{q^{n}}$. In nearfield theory the two
distributive laws can not hold at the same time. So in term of left nearfield
and near-ring, the right distributivity does not hold and to solve the problem,
we defined a set of all distributive elements called $D(R)$.
