The domain oemc.pl is the foundation of a comprehensive database of mathematical constants created in Poland by Artur Jasinski.
OEMC maintains an extensive catalog of mathematical constants, including well-known numbers like π, e, and the Euler–Mascheroni constant γ, as well as many lesser-known constants arising in analytic number theory, combinatorics, and special functions.
The site provides alternative definitions and known properties of constants, serving as a comprehensive research and reference tool for mathematicians. It is particularly useful for verifying conjectured numerical constants, identifying closed forms, and cross-referencing with sequences and series related to constants.
The database also serves as a repository to identify and correct errors found in mathematical literature.
OEMC contains constants from both published literature and specialized databases, many of which appear in advanced analytic formulas, integrals, infinite series, sums, products, and limits.
Researchers can use OEMC to confirm whether a numerical approximation corresponds to a known constant, explore relationships between constants, and understand their occurrence throughout mathematical literature.
The website oemc.pl is significant as it hosts the Online Encyclopedia of Mathematical Constants, acting as a centralized, searchable repository for mathematical constants, their properties, and relationships. It is an invaluable resource for mathematicians exploring transcendental numbers, algebraic constants, and numerical approximations.
