wedge complements in finite dimension


in the next counting experiment we are going  to calculate the dimensions of some linear subspaces of the Grassmann algebra of a vector space of dimension n.

We should  be using the intuition granted by \Lambda(\mathbb{R}^n)

The definitions are:

  • C_{dx}=\{\alpha\mid \alpha\wedge dx=0\}
  • M_{dx}={C_{dx}}^{\top}
  • C_{dx\wedge dy}=\{\alpha\mid \alpha\wedge dx\wedge dy=0\}
  • M_{dx\wedge dy}={C_{dx\wedge dy}}^{\top}
  • C_{dx\wedge dy\wedge dz}
  • M_{dx\wedge dy\wedge dz}

doesn’t anybody know the name of the result?…  ‘cuz if it hasn’t, I will claim mine : )

Meanwhile, let me refrain the definition  that says:  

\Lambda(\Omega) 

is the C^{\infty}(\Omega)module over the symbols dx^1,dx^2,...,dx^n and over an open set \Omega\subseteq\mathbb{R}^n

stay tune…

    i think that C_{dx} could be called the Ann(dx) in \Lambda(R^n): the annihilator
