Замкнутое линейное подпространство H ⊆ C( G) называется инвариантным подпространством, если оно инвариантно относительно сдвигов τ y : f( x) ↦ f( x + y) , y ∈ G . В работе доказывается, что любое инвариантное подпространство H допускает спектральный синтез, то есть H совпадает с замыканием линейной оболочки всех содержащихся в H характеров группы G .</p></abstract><trans-abstract xml:lang="en"><p>Let G be a zero-dimensional locally compact Abelian group whose elements are compact, C(G) the space of continuous complex-valued functions on the group G . A closed linear subspace H ⊆ C(G) is called invariant subspace, if it is invariant with respect to translations τ y : f(x) ↦ f(x + y) , y ∈ G . We prove that any invariant subspace H admits spectral synthesis, which means that H coincides with the closure of the linear span of all characters of the group G contained in H .</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нульмерные группы</kwd><kwd>характеры</kwd><kwd>гармонический анализ</kwd><kwd>спектральный синтез</kwd><kwd>инвариантные подпространства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>zero-dimensional groups</kwd><kwd>characters</kwd><kwd>harmonic analysis</kwd><kwd>spectral synthesis</kwd><kwd>invariant subspaces</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">L.
