There is traditional vector calculus of 3D vectors:
In this calculus we usually operate with 3-dimensional vectors and scalars.
But can we consider a sum of a vector and a scalar and define operations on them in such a way so that the vector calculus identities were generalized?
In other words, an algebra of elements of the form
$\mathbf{V}=a_0+a_1\mathbf{i}+a_2\mathbf{j}+a_3\mathbf{k}=a_0+\mathbf{v}$
There still would be dot and cross products (dot product still always scalar):
$\mathbf{V_1}\cdot \mathbf{V_2}=(a_0+\mathbf{v_1})\cdot(b_0+\mathbf{v_2})=a_0 b_0+\mathbf{v_1}\cdot\mathbf{v_2}$
$\mathbf{V_1}\times \mathbf{V_2}=(a_0+\mathbf{v_1})\times(b_0+\mathbf{v_2})=a_0 \mathbf{v_2}+b_0\mathbf{v_1}+\mathbf{v_1}\times\mathbf{v_2}$
Norm: $||\mathbf{V}||=\sqrt{a_0^2+||\mathbf{v}||^2}=\sqrt{\mathbf{V}\cdot\mathbf{V}}$
And so on.
I wonder, what properties such algebra would have, can we define elementary functions in this space, particularly, logarithms, and how will it compare with hypercomplex numbers.
