Meromorphic (/ˌmɛrəˈmɔrfɪk/) is a mathematical term that refers to a kind of complex function that is complex analytic except at a finite number of singular points, which are poles. The term is derived from the Greek root "meros" meaning "part" and "morfe" meaning "shape" or "form". The spelling of meromorphic follows the usual English pronunciation conventions for combining syllables with common prefixes and stems. The use of the IPA phonetic transcription helps understand how each sound and syllable in the word is pronounced correctly.
Meromorphic is an adjective in mathematics that is commonly used to describe a function, particularly in complex analysis. It refers to a function that is both holomorphic (or analytic) on the whole complex plane except for a set of isolated singularities, and it remains bounded in the neighborhood of each of these singularities.
A meromorphic function is characterized by its ability to be represented as a ratio of two holomorphic functions. In other words, for any given point in the complex plane, the function is either holomorphic or has a pole at that point. However, it is important to note that a meromorphic function can have poles of different orders, which determines the nature of the singularity.
The term "meromorphic" combines the Latin word "mero," meaning partial or broken, and the Greek word "morphe," translating to form. Thus, it describes a function that is partially analytic and partially having singularities.
Meromorphic functions often arise in complex analysis and have applications in various mathematical fields, including algebraic geometry, number theory, and physics. They offer a powerful tool for analyzing complex functions, as they capture the behavior of functions that are not necessarily holomorphic everywhere, but still possess regularity properties beyond meromorphic functions.
Overall, a meromorphic function is a mathematical function that is both analytic and has isolated singularities, making it a significant concept in complex analysis.
The word "meromorphic" is derived from the combination of two Greek roots: "meros" (meaning part) and "morfe" (meaning shape or form).
In mathematics, specifically in complex analysis, "meromorphic" describes a function that is defined and holomorphic (complex-differentiable) in all points of its domain except for a finite number of isolated poles. The term reflects the fact that such a function can be seen as a combination of two types of functions: "mero-" indicating that it has parts that are analytic (holomorphic) and parts that are non-analytic (poles).
