816. Visibility polynomials, dual visibility spectrum, and characterization of total mutual-visibility setsCsilla Bujtás, Sandi Klavžar, Jing Tian, 2025, original scientific article Abstract: Mutual-visibility sets were motivated by visibility in distributed systems and social networks, and intertwine with several classical mathematical areas. Monotone properties of the variety of mutual-visibility sets, and restrictions of such sets to convex and isometric subgraphs are studied. Dual mutual-visibility sets are shown to be intrinsically different from other types of mutual-visibility sets. It is proved that for every finite subset $Z$ of positive integers there exists a graph $G$ that has a dual mutual-visibility set of size ▫$i$▫ if and only if $i\in Z\cup \{0\}$, while for the other types of mutual-visibility such a set consists of consecutive integers. Visibility polynomials are introduced and their properties derived. As a surprise, every polynomial with nonnegative integer coefficients and with a constant term $1$ is a dual visibility polynomial of some graph. Characterizations are given for total mutual-visibility sets, for graphs with total mutual-visibility number $1$, and for sets which are not total mutual-visibility sets, yet every proper subset is such. Along the way an earlier result from the literature is corrected.
Keywords: mutual-visibility sets, variety of mutual-visibility sets, convex subgraphs, integer polynomial

818. Counting largest mutual-visibility and general position sets of glued $t$-ary treesSandi Klavžar, Aparna Lakshmanan S., Dhanya Roy, 2025, original scientific article Abstract: All four invariants of the mutual-visibility problem and, all four invariants of the general position problem are determined for glued binary trees. The number of the corresponding extremal sets is obtained in each of the eight situations. The results are further extended to glued $t$-ary trees, and some of them also to generalized glued binary trees.
