Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

ABSTRACT This paper considers a generalized system of second‐order partial differential equations of hypergeometric type that encompasses all 34 Horn series in two variables. Using the modified FrobeniusLatysheva method, we analyze the behavior of solutions near singular points and curves. Conditions for the existence and structure of solutions in the form of generalized power series are obtained, along with recurrence relations for the coefficients. Examples of hypergeometric functions of types , and are provided to validate the proposed approach. The results are of interest for studies in mathematical physics and the theory of special functions.
