NettetLineality space, De nition: lin(C) := rec(C)\( rec(C)) is called the lineality space of C. It is a subspace. So lin(C) consists of all direction vectors of lines that are contained in C(the zero vector is included) Polyhedra: rec(fx: Ax bg) = fx: Ax Og. Example: Hyperplane H = fx2Rn: aTx= g. Then rec(H) = lin(H) = fag?

Nettetlineality space of some nonempty section K(y), i.e., the largest sub-space of En for which a translate is contained in K(y), and let L* be the subspace of En orthogonal to L. It is easily shown that L is in fact the lineality space of every nonempty section K(y) and is contained in the lineality space of P. Thus P is the vector sum of L and the NettetThe moduli space M 0;n can be given the structure of a tropical fan (see Remark 2.3 for the fan structure) of dimension n 3 in a quotient space of R(n 2) ([GKM, Theorem 3.7]); in fact, it can be described as the tropical Grassmannian G(2;n)modulo its lineality space (see [SS, Theorem 3.4] or [GKM, Remark 3.9]). the merger enforcement improvement act
