Построение явных решений (2+1)-мерного обобщенного уравнения Бенджамина-Оно не только обеспечивает теоретическую поддержку экспериментальным исследованиям, но и дает строгую основу для решения прикладных задач, возникающих в нелинейной динамике волн. В данной работе исследовано распространение волн, описываемое (2+1)-мерным обобщенным уравнением Бенджамина-Оно в нелинейных средах с учетом дисперсионных эффектов. Для этого в качестве аналитических инструментов получения явных решений используются метод функций синуса-косинуса и метод гиперболического тангенса. Показано, что эти методы эффективны для широкого класса нелинейных уравнений математической физики. С их помощью получены решения в виде периодических волн и уединенных волн; для графического представления результатов построены трехмерные и двумерные графики при выборе подходящих значений параметров модели.</p></abstract><trans-abstract xml:lang="en"><p>The (2+1)-dimensional generalized Benjamin-Ono equation models the propagation of small-amplitude, long-wavelength waves on the surface of shallow water. Constructing explicit solutions of the (2+1)-dimensional generalized Benjamin-Ono equation not only provides theoretical support for experimental investigations but also offers a rigorous basis for addressing applied problems arising in nonlinear wave dynamics. In this work, we investigate wave propagation governed by the (2+1)-dimensional generalized Benjamin-Ono equation in nonlinear media, accounting for dispersive effects. To this end, the sine-cosine function method and the hyperbolic tangent method are employed as analytical tools for deriving explicit solutions. The methods prove effective for a broad class of nonlinear equations encountered in mathematical physics. Using these approaches, periodic-wave solutions and solitary wave solutions are obtained, and to illustrate the obtained results, we plot 3D and 2D plots by setting suitable values of the involved parameters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>обобщенное уравнение Бенджамина-Оно</kwd><kwd>метод синусов и косинусов</kwd><kwd>метод гиперболического тангенса</kwd><kwd>решение в виде периодической волны</kwd><kwd>решение в виде солитонной волны</kwd></kwd-group><kwd-group xml:lang="en"><kwd>generalized Benjamin-Ono equation</kwd><kwd>sine-cosine method</kwd><kwd>hyperbolic tangent method</kwd><kwd>periodic wave solution</kwd><kwd>solitary wave solution</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This work is supported by the Ministry of Science and Higher Education of the Republic of Kazakhstan (grant AP26194665)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wazwaz, A.M., Partial Differential Equations and Solitary Waves Theory (Springer-Verlag, Berlin Heidelberg, 2009), 681 p.</mixed-citation><mixed-citation xml:lang="en">Wazwaz, A.M., Partial Differential Equations and Solitary Waves Theory (Springer-Verlag, Berlin Heidelberg, 2009), 681 p.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Burdik, C., Shaikhova.
