undholomorphicity

Undholomorphicity is a concept within complex analysis that describes a type of generalized holomorphicity. While a standard holomorphic function is complex differentiable in the traditional sense, an undholomorpic function may exhibit differentiability in a weaker, more generalized way. This concept often arises in the study of Sobolev spaces and their extensions to complex domains.

The precise definition of undholomorphicity can vary depending on the context, but it typically involves a notion of weak differentiability or differentiability in a distributional sense. Instead of requiring the pointwise limit of the difference quotient to exist, undholomorphicity might be defined through integration against test functions or by satisfying certain integral conditions. This allows for functions that are not classically differentiable but still possess desirable analytical properties.

Undholomorphicity plays a role in various areas of mathematics, including the theory of partial differential equations, harmonic analysis, and geometric function theory. It provides a framework for studying functions that may have singularities or lack smoothness in the classical sense, yet still exhibit a form of analytic behavior. The study of undholomorphic functions often involves adapting standard techniques from complex analysis to accommodate these weaker regularity conditions.
