П. Романовым для доказательства его теоремы о том, что нижняя асимптотическая плотность суммы множества простых и множества степеней фиксированного натурального числа положительна, которая также позволяет заменить в этой теореме второе множество другим — с похожими распределением и арифметикой. Описываются условия на второе множество, достаточные для получения аналога теоремы, и приводится пример множества с похожим распределением, но с другой арифметикой, для которого эти достаточные условия не выполняются. Доказывается, что для указанного множества аналог теоремы Романова неверен.</p></abstract><trans-abstract xml:lang="en"><p>In paper we describe the way N. P. Romanoff proved his additive theorem and sufficient conditions to obtain its analogues for sets with similar distribution and arithmetic. Also the example of set with similar distribution but with different arithmetic is given. We prove that the Romanoff theorem’s analogue for this set is incorrect.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>теорема Романова</kwd><kwd>сумма множеств</kwd><kwd>тригонометрические суммы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Romanoff theorem</kwd><kwd>sumset</kwd><kwd>exponential sums</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">Романов Н.
