### Lucas graphs

Special number sequences play important role in many areas of science. One of them named as Fibonacci sequence dates back to 820 years ago. There is a lot of research on Fibonacci numbers due to their relation with the golden ratio and also due to …

### New results on symmetric division deg index

The symmetric division deg index (or simply sdd-index) was proposed by Vukičević et al. as a remarkable predictor of total surface area of polychlorobiphenyls. It is one of discrete Adriatic indices that showed good predictive properties on the …

### Cacti with maximal general sum-connectivity index

Let V(G) and E(G) be, respectively, the vertex set and edge set of a graph G. The general sum-connectivity index of a graph G is denoted by $$\chi _\alpha (G)$$ χ α ( G ) and is defined as $$\sum \limits _{uv\in E(G)}(d_u+d_v)^\alpha$$ ∑ u v ∈ E …

### The minimum Hamming distances of repeated-root cyclic codes of length and their MDS codes

In this paper, let p be a prime with $$p\ge 7$$ p ≥ 7 . We determine the weight distributions of cyclic codes of length 6 over $$\mathbb {F}_q$$ F q and the minimum Hamming distances of all repeated-root cyclic codes of length $$6p^s$$ 6 p s over …

### Periodic solution and dynamical analysis for a delayed food chain model with general functional response and discontinuous harvesting

In this paper, a delayed food chain model with general functional response and discontinuous harvesting is considered. Under some reasonable assumptions, one proves the positivity and boundedness of the solutions. Moreover, the sufficient …
