Представлены подходящие для таких задач два типа адаптированных к слою сеток. Для обоих типов даны равномерные оценки погрешности в ε-весовой энергетической норме для конечных элементов высокого порядка. В целях сравнения этих сеток и подтверждения теоретических выводов использованы численные эксперименты.Статья публикуется в авторской редакции.</p></abstract><trans-abstract xml:lang="en"><p>We consider singularly perturbed turning point problems whose solutions exhibit an interior layer. Two suitable layer-adapted mesh-types are presented. For both types we give uniform error estimates in the ε-weighted energy norm for ﬁnite elements of higher order. Numerical experiments are used to compare the meshes and to conﬁrm the theoretical ﬁndings.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сингулярные возмущения</kwd><kwd>точка поворота</kwd><kwd>внутренний слой</kwd><kwd>адаптированные к слою сетки</kwd><kwd>конечные элементы высокого порядка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>singular perturbation</kwd><kwd>turning point</kwd><kwd>interior layer</kwd><kwd>layer-adapted meshes</kwd><kwd>higher order ﬁnite elements</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">Becher S., “Analysis of Galerkin and SDFEM on piecewise equidistant meshes for turning point problems exhibiting an interior layer”, 2016, arXiv:1604.01327v1 [math.NA].</mixed-citation><mixed-citation xml:lang="en">Becher S., “Analysis of Galerkin and SDFEM on piecewise equidistant meshes for turning point problems exhibiting an interior layer”, 2016, arXiv:1604.01327v1 [math.NA].</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Becher S., “FEM-analysis on graded meshes for turning point problems exhibiting an interior layer”, 2016, https://arxiv.org/abs/1603.04653v1.</mixed-citation><mixed-citation xml:lang="en">Becher S., “FEM-analysis on graded meshes for turning point problems exhibiting an interior layer”, 2016, https://arxiv.org/abs/1603.04653v1.</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">Berger A.
