Найден общий вид p-голоморфной функции. Получены достаточные условия p-аналитичности и локальной обратимости. Доказаны принципы сохранения области и максимума нор- мы для p-голоморфной функции и теорема единственности.</p></abstract><trans-abstract xml:lang="en"><p>In this article the relationship between the conditions of p-differentiability, p-holomorphycity, and the existence of the derivative of a function of a p-complex variable is considered. The general form of a p-holomorphic function is found. The sufficient conditions for p-analyticity and local invertibility are obtained. The open mapping theorem and the principle of maximum of the norm for a p-holomorphic function and the uniqueness theorem are proved.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дуальные числа</kwd><kwd>кольцо p-комплексных чисел</kwd><kwd>p-комплексные функции</kwd><kwd>делители нуля</kwd><kwd>p-голоморфность</kwd><kwd>p-аналитичность</kwd><kwd>локальная обратимость</kwd><kwd>принцип сохранения области</kwd><kwd>принцип максимума нормы</kwd><kwd>теорема единственности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dual numbers</kwd><kwd>ring of p-complex numbers</kwd><kwd>p-complex functions</kwd><kwd>zero divisors</kwd><kwd>p-holomorphycity</kwd><kwd>p-analyticity</kwd><kwd>local invertibility</kwd><kwd>domain preservation principle</kwd><kwd>open mapping theorem</kwd><kwd>norm maximum principle</kwd><kwd>uniqueness theorem</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.
