Abstract

The Beta function is part of a special function in the form of an integral statement and the result form is twice the multiplication of factorial functions. The Beta function is part of an unnatural integral because it has infinite-value parameters, resulting in infinite functions. Beta function is symbolized as β which basically can be defined in real and complex numbers with certain conditions. Completion of Beta functions can use residues. Residue is the residual product of an equation that has a singular point. Residues are used in calculating the integration of complex functions on unnatural integrals. Then the residue can complete the Beta function. Residues in the Beta function use the analysis of the concept of residues by determining the convergence, analytical, and kesingularitas areas of the Beta function, a Beta function domain is obtained. The domain area can be used in expanding the Laurent series. Then you will get a pole or pole that will affect the calculation in obtaining residuals. Based on the results of the study, the Beta function has a singular point that causes the point is not analytic to the Beta function. The singular point occurs at the point , then the residual form in the Beta function with the n-level pole and the singular point forms the equation, ( dengan . and the parameter value contains infinite positive integers, then for each positive integer value entered in the Beta function produces a zero value residue. Keywords: Beta function, residue

Abstract

This research aims to analyze cultural interactions between traders and buyers at the Medan Central Market in facing the rise of digital-based economic markets. Digital transformation and the growth of e-commerce have had a significant impact on trade patterns and consumer behavior, especially in traditional markets. The research method used is a qualitative approach with data collection techniques through in-depth interviews, participant observation and documentation. The research was conducted at the Medan Central Market with research subjects including textile wholesalers and consumers. The research results show that although digitalization has made transactions easier and expanded market reach, many traditional market traders have experienced a decline in income of up to 50% due to reduced customers. However, cultural interactions involving the bargaining process and personal relationships between traders and buyers remain the advantages of traditional markets. On the other hand, the adoption of digital technology by some traders is starting to help increase their competitiveness, although they are still hampered by digital infrastructure and literacy. This research emphasizes the importance of government support in providing digital training and infrastructure, as well as the need for a balanced adaptation strategy to maintain the cultural value of traditional markets in the digital era.
