SNC

SNC is an acronym with multiple meanings across different domains, and its exact reference depends on the context in which it is used. In capitalization, it is sometimes written as SNC or snc.

In mathematics and algebraic geometry, SNC stands for simple normal crossings. This term describes a type of divisor on a smooth variety where the irreducible components meet transversely and locally resemble coordinate hyperplanes. An snc (simple normal crossings) divisor is a standard object in the study of singularities and resolutions.

In business and industry, SNC-Lavalin Group Inc. is a prominent Canadian engineering and construction company. In financial and corporate contexts, the company is often abbreviated as SNC, although its full name is commonly used in official communications. The firm operates internationally and is involved in infrastructure, engineering, and project management.

In rail and transportation history, the acronym SNC has appeared in the names of national railway entities in various European contexts, particularly in reference to national rail organizations prior to the consolidation or rebranding that created more centralized operators such as SNCF in France. The use of SNC in this sense is historical and varies by country.

Because SNC can refer to diverse concepts—mathematical terminology, a major corporation, or historical railway designations—its meaning is determined by surrounding information such as field, geography, and subject matter. When encountering snc, readers should rely on context to identify the intended reference.
