The wall has a finite number of small windows. We consider resonance states localized near each window. The presence of several windows forces one to describe their common influence differently from that of the single-window case. Using the “matching of asymptotic expansions” method, we derive formulas for resonances and resonance states.</p></abstract><trans-abstract xml:lang="ru"><p>Рассмотрена пара связанных квантовых волноводов с общей полупрозрачной стенкой. В стенке имеется конечное число малых отверстий. Рассматриваются резонансные состояния, сосредоточенные около каждого отверстия. Наличие нескольких отверстий требует описания их взаимного влияние в отличие от случай одного отверстия. Используя метод согласования асимптотических разложений, мы выводим формулы для резонансов и резонансных состояний.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>резонанс</kwd><kwd>резонансное состояние</kwd><kwd>волновод</kwd><kwd>асимптотика</kwd><kwd>полупрозрачность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>resonance</kwd><kwd>resonance state</kwd><kwd>waveguide</kwd><kwd>asymptotics</kwd><kwd>semitransparency</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">Lord Rayleigh O.M.
