Jensen-type inequalities for convex and $m$ -convex functions via fractional calculus

Yamilet Quintana, José M. Rodríguez, José M. Sigarreta Almira

Inequalities play an important role in pure and applied mathematics. In particular, Jensen's inequality, one of the most famous inequalities, plays a main role in the study of the…

A note on total co-independent domination in trees

Abel Cabrera Martínez, Frank A. Hernández Mira, José M. Sigarreta Almira +1

A set $D$ of vertices of a graph $G$ is a total dominating set if every vertex of $G$ is adjacent to at least one vertex of $D$ . The total domination number of $G$ is the minimum c…

Defensive k-alliances in graphs

J. A. Rodriguez-Velazquez, I. G. Yero, J. M. Sigarreta

Let $Γ = (V, E)$ be a simple graph. For a nonempty set $X \subseteq V$ , and a vertex $v \in V$ , $δ_{X} (v)$ denotes the number of neighbors $v$ has in $X$ . A nonempty set $S \subseteq V$ …
