The current volume is a comprehensive collection showcasing the latest advancements in the fields of Analysis and Partial Differential Equations (PDE) in Latin America. This book, which continues the series dedicated to Latin American mathematical research, highlights innovative perspectives from this vibrant community. It features contributions from leading researchers, each providing new insights and exploring future directions in Analysis and PDE. The book aims to bring greater visibility to the substantial mathematical activity in Latin America, which is often published in Spanish and remains less known in the broader mathematical literature typically written in English. It provides a unique view into the dynamic research landscape of Latin America, highlighting both theoretical advancements and practical applications, such as models for epidemics, population dynamics, climatological risks, and medical diagnostics. Analysis and PDE are highly active areas in mathematics due to their wide-ranging applications, from physical phenomena like heat diffusion to biological models describing the cardiovascular system. These fields, with over 200 years of tradition, are deeply integrated with modern numerical methods and are linked to problems in artificial intelligence, big data, and control theory. Latin America, with its vast Spanish-speaking community and significant mathematical output, is a key player in these fields. This book aims to popularize the region's innovative research, presenting important results from young and established Latin American mathematicians. Their work addresses local challenges with global relevance, providing insights valuable to other regions with similar conditions. In particular, this book includes contributions from some speakers at the ICMAM Latin America 2025 conference.
