Let \( P_h \) be a path on \( h \) vertices. A simple graph \( G = (V, E) \) admits a \( P_h \)-covering if every edge in \( E \) belongs to a subgraph of \( G \) that is isomorphic to \( P_h \). \( G \) is called \( P_h \)-magic if there is a total labeling \( f: V \cup E \to \{1, 2, \dots, |V| + |E|\} \) such that for each subgraph \( H’ = (V’, E’) \) of \( G \) that is isomorphic to \( P_h \), \( \sum_{v \in V’} f(v) + \sum_{e \in E’} f(e) \) is constant. When \( f(V) = \{1, 2, \dots, |V|\} \), we say that \( G \) is \( P_h \)-supermagic.
In this paper, we study some \( P_h \)-supermagic trees. We give some sufficient or necessary conditions for a tree to be \( P_h \)-supermagic. We also consider the \( P_h \)-supermagicness of special types of trees, namely shrubs and banana trees.
