Практическая значимость — в задачах мониторинга распространения информации, оценки структурной уязвимости сетей и прогнозирования каскадных сбоев в многослойных структурах (социальные платформы, транспортные и коммуникационные сети). ограничения связаны с предположением о распространении по кратчайшим путям, априорной агрегацией слоев и отсутствием учета временной динамики. </p></abstract><trans-abstract xml:lang="en"><p>The paper proposes a theoretically grounded and computationally efficient algorithm for identifying critically important (“bridge”) edges in multilayer social graphs. The approach consists of three sequential procedures: 1) spectral coarsening of each graph layer — compression while preserving key spectral properties (in particular, the Laplacian) and the local resistive structure; 2) approximate estimation of edge betweenness centrality — computing edge importance with layer weights and cross-layer interactions taken into account; 3) greedy shortest-path coverage — iteratively selecting edges that maximize graph fragmentation while minimizing the number of removals. The key properties of the algorithm are established: it preserves above-threshold connectivity of the residual graph (via control of the second Laplacian eigenvalue); limits the growth of the effective diameter after edge removals; provides a (1–1 / е) approximation to the optimal shortest-path cover; is robust to noise perturbations and variations in layer weights; and has asymptotic complexity O(Ln log n + km log n), which is substantially lower than that of classical methods. The practical significance lies in monitoring information diffusion, assessing structural vulnerability, and predicting cascading failures in multilayer infrastructures (social platforms as well as transportation and communication networks). Limitations include the assumption of shortest-path propagation, a priori layer aggregation, and the lack of an explicit temporal dynamics model.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многослойный (мультиплексный) социальный граф</kwd><kwd>посредническая центральность ребра</kwd><kwd>спектральное укрупнение (coarsening)</kwd><kwd>критические мостовые ребра («мосты влияния»)</kwd><kwd>сублинейная сложность вычислений</kwd><kwd>межкластерные ребра</kwd><kwd>жадное покрытие путей</kwd><kwd>лапласиан графа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multilayer (multiplex) social graph</kwd><kwd>intermediary edge centrality</kwd><kwd>spectral coarsening</kwd><kwd>critical bridging edges (“bridges of influence”)</kwd><kwd>sublinear computational complexity</kwd><kwd>intercluster edges</kwd><kwd>greedy path coverage</kwd><kwd>graph Laplacian</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Newman M.E.J., Girvan M.
