$b$ -vectors of chordal graphs

Luis Pedro Montejano, Luis Núñez Betancourt

The $b$ -vector $(b_{1}, b_{2} \dots, b_{d})$ of a graph $G$ is defined in terms of its clique vector $(c_{1}, c_{2} \dots, c_{d})$ by the equation $\sum^d_{i=1}b_i(x+1)^{i-1}=\sum^d_{i=1} c_i x^{i…

Shadows of a Closed Curve

Michael Gene Dobbins, Heuna Kim, Luis Montejano +1

A shadow of a geometric object $A$ in a given direction $v$ is the orthogonal projection of $A$ on the hyperplane orthogonal to $v$ . We show that any topological embedding of a cir…
