@misc{10498/37615, year = {2026}, url = {http://hdl.handle.net/10498/37615}, abstract = {A vertex set in a graph without isolated vertices is a total restrained dominating set (TRD-set) if it is dominating, induces a subgraph without isolated vertices, and the vertices not in the set also induce a subgraph without isolated vertices. Two vertex sets, which are not TRD-sets, form a total restrained coalition if their union is a TRD-set. A total restrained coalition partition is a partition where none of its elements are TRD-sets, but each forms a total restrained coalition with another element. The goal is to maximize the cardinality of such a partition, denoted C tr (G). We initiate the study of this concept by proving certain properties, extremal values, general bounds, and its relation to known structural parameters. Exact values for specific graph families are also provided.}, publisher = {Springer}, keywords = {Coalition}, keywords = {Total restrained coalition}, keywords = {Total restrained dominating set}, title = {Total restrained coalitions in graphs}, doi = {10.1007/s40314-025-03439-w}, author = {Chellali, M. and Golmohammadi, H. and Matrokhin, N.A. and Takhonov, I. and Valenzuela Tripodoro, Juan Carlos}, }
