The Neuman systems model is a nursing theory based on the individual's relationship to stress, the reaction to it, and reconstitution factors that are dynamic in nature. [1] The theory was developed by Betty Neuman, a community health nurse, professor and counselor. The central core of the model consists of energy resources (normal temperature ...
The series is named after the mathematician Carl Neumann, who used it in 1877 in the context of potential theory. The Neumann series is used in functional analysis . It is closely connected to the resolvent formalism for studying the spectrum of bounded operators and, applied from the left to a function, it forms the Liouville-Neumann series ...

Carl Gottfried Neumann (also Karl; 7 May 1832 – 27 March 1925) was a German mathematical physicist and professor at several German universities. His work focused on applications of potential theory to physics and mathematics.
The function f(x, y) = x 2 − y 2 is concave-convex.. Von Neumann's minimax theorem can be generalized to domains that are compact and convex, and to functions that are concave in their first argument and convex in their second argument (known as concave-convex functions).
However, four decades passed before Neumann elaborated his application of symmetry in a course on elasticity in 1873. This principle was later formalized by his student Woldemar Voigt (1850–1918) in 1885: " the symmetry of the physical phenomenon is at least as high as the crystallographic symmetry ", which became a fundamental postulate of ...
In mathematics, the HNN extension is an important construction of combinatorial group theory.. Introduced in a 1949 paper Embedding Theorems for Groups [1] by Graham Higman, Bernhard Neumann, and Hanna Neumann, it embeds a given group G into another group G' , in such a way that two given isomorphic subgroups of G are conjugate (through a given isomorphism) in G' .
