Abstract: The Randic type additive connectivity matrix of the graph $G$ of order $n$ and size $m$ is defined as $RA(G)=(R_{ij})$, where $R_{ij}=\sqrt{d_{i}}+\sqrt{d_{j}}$ if the vertices $v_i$ and $v_j$ are adjacent, and $R_{ij}=0$ if $v_i$ and $v_j$ are not adjacent, where $d_i$ and $d_j$ be the degrees of vertices $v_i$ and $v_j$ respectively. The purpose of this paper is to introduce and investigate the Randic type additive connectivity energy of a graph. In this paper, we obtain new inequalities involving the Randic type additive connectivity energy and presented upper and lower bounds for the Randic type additive connectivity energy of a graph. We also report results on Randic type additive connectivity energy of generalized complements of a graph.

Key words: Randic type additive connectivity energy, Randic type additive connectivity eigenvalues.
