Abstract
We will give an explicit description of extensions of the group scheme (resp.\ the formal group scheme) which gives a deformation of the additive group scheme to the multiplicative group scheme (resp.\ the additive formal group scheme to the multiplicative formal group scheme) by the additive group scheme (resp.\ the additive formal group scheme) over an algebra for which all prime numbers except a given prime $p$ is invertible.
