Сформулированы и доказаны теоремы о глобальной первообразной и равномерном приближении h-голоморфных функций многочленами. Получены достаточные условия h-голоморфности предельной функции. Сформулированы и доказаны принцип компактности для функций h-комплексного переменного и аналог теоремы Витали для h-аналитических функций.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, we consider the properties of uniformly convergent sequences of h-holomorphic functions on the set of h-complex numbers. Theorems on the global antiderivative and on the uniform approximation of h-holomorphic functions by polynomials are formulated and proven. The sufficient conditions for the h-holomorphism of the limit function are obtained. The compactness principle for functions of an h-complex variable and an analog of Vitaliʼs theorem for h-analytic functions are formulated and proven.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кольцо h-комплексных чисел</kwd><kwd>h-голоморфные функции</kwd><kwd>делители нуля</kwd><kwd>равномерная сходимость</kwd><kwd>последовательность h-голоморфных функций</kwd><kwd>функциональный ряд</kwd><kwd>принцип компактности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ring of h-complex numbers</kwd><kwd>h-holomorphic functions</kwd><kwd>zero divisors</kwd><kwd>uniform convergence</kwd><kwd>sequence of h-holomorphic functions</kwd><kwd>compactness principle</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">Яглом, И.
