Scheffers

In mathematics, "Scheffers" is most commonly associated with several concepts attributed to the German mathematician Georg Scheffers (1866-1945). These concepts include, but are not limited to:

• Scheffers' Theorem: A theorem in differential geometry related to ruled surfaces. It states conditions under which a ruled surface is developable.

• Scheffers Class: A class of ordinary differential equations that can be solved by quadrature. These equations have a specific form which allows for integration to find solutions.

• Lie-Scheffers Theorem: This theorem is about the complete integrability of Pfaffian systems. It provides conditions under which a system of differential forms can be integrated, meaning a solution can be found.

• Other contributions: Scheffers also worked in areas such as linear algebra, foundations of geometry, and nomography. While not always directly named after him, his contributions impacted these areas.

Because the name "Scheffers" is linked to several different mathematical concepts, it's important to specify the context to avoid ambiguity. Referencing the full name (Georg Scheffers) or the specific theorem/class/concept in question is recommended for clarity.
