Hatáselemzés

Hatáselemzés is a Hungarian term meaning boundary analysis, used in several scientific disciplines to describe the study of boundaries, interfaces, or thresholds that influence a system or problem. In mathematics and related fields, hatáselemzés typically refers to aspects that are determined by the boundary of a domain or by boundary data. Core topics include the classification and properties of boundary points (topological or measure-theoretic boundaries), boundary conditions for differential equations (such as Dirichlet, Neumann, and Robin conditions), and the relationship between interior solutions and information specified on the boundary, as captured by trace theorems and boundary value problems. The term also appears in potential theory and complex analysis, where the behavior of functions on or near the boundary is of central interest.

In applied contexts, hatáselemzés underpins modeling and analysis where boundary interactions matter, including heat conduction, fluid dynamics, electromagnetism, and structural mechanics. In numerical analysis, approaches that rely on boundary information to solve equations on a domain are often described using this broader notion, though exact terminology can vary by subfield.

Etymology: from határ (boundary, limit) and elemzés (analysis). The precise meaning of hatáselemzés can differ across disciplines, and Hungarian literature may pair it with more specific descriptors.
