WebJan 10, 2024 · We can draw a graph with the help of the incidence matrix. The algebraic sum of elements of all the columns is zero. The rank of the incidence matrix is (n–1). The determinant of the incidence matrix of a closed loop is zero. Hence, Only statement I is correct. Example: Consider the below-closed graph: The incidence matrix is written as: WebDenote the incidence vector of $F$ in $\mathbb {R}^E$ by $\chi^F$, i.e. for any edge $e$ in $E$, $\chi^F (e)=1$ if $e\in F$ and $\chi^F (e)=0$ otherwise. Considering $w$ as a vector in in $\mathbb {R}^E$ we have $w (F)=w^T\chi^F$. My doubts are as follows: Is $E$ a vector space and $w,\chi^F$ linear transformations from $E$ to $\mathbb {R}$?

Incidence. In a graph , two edges are incident if they share a common vertex. For example, edge and edge are incident as they share the same vertex . Also, we can define the incidence over a vertex. A vertex is an incident to an edge if the vertex is one of the two vertices the edge connects.
