eccentricity
eccentricity (ɛksɛnˈtrɪsɪtɪ) [f. as prec. + -ity.] The state or quality of being eccentric, q.v. 1. The quality of being abnormally centred; of not being concentric; of not having the axis in the centre. † Orig. of planetary orbits: The fact of having the earth at a distance from the centre (Obs. ex...

Eccentricity (behavior)
Eccentricity (also called quirkiness) is an unusual or odd behavior on the part of an individual. Eccentricity is also associated with great wealth — what would be considered signs of insanity in a poor person, some may accept as eccentricity in wealthy wikipedia.org

Angular eccentricity
It may be defined in terms of the eccentricity, e, or the aspect ratio, b/a (the ratio of the semi-minor axis and the semi-major axis): Angular eccentricity Any non-dimensional parameter of the ellipse may be expressed in terms of the angular eccentricity. wikipedia.org

Horizontal eccentricity
Horizontal eccentricity refers to the horizontal axis, measured in degrees, along the visual field. The blind spot extends from an eccentricity d1 to eccentricity d2 in temporal direction from the fovea. wikipedia.org

Significance of negative eccentricity For any conic section, the eccentricity is the ratio of the distance to the focus and directrix. If the eccentricity were defined to be negative, would this have any significant m...
If you make a plot of a conic section based on the eccentricity, it doesn't change at all. Nothing happens if you negate the eccentricity. formula for eccentricity#Values)

Eccentricity of vertices in a regular graph I was just trying to find out the eccentricity of the vertices in regular graphs, given in the link < Surprisingly, eccentricity is the same in all graphs except < I checked...
Take $K_4$ and subdivide one edge (put a vertex of degree two in the middle of it). Now take two copies of the subdivided graph and add an edge joining the two vertices of valency two. This new graph is cubic on 10 vertices and the eccentricities range from 3 to 5. This construction is easy to gener...

Eccentricity of vertices in a graph when eccentricity of one vertex is given I have a very basic doubt. If a vertex in any graph has the eccentricity two, then what can be concluded about eccentricities of other verti...
The eccentricity of every other vertex can be $4$, as looking at a path of length $5$ will tell you (there, the third element has eccentricity of $2$, while the edges have an eccentricity of $4$).

Eccentricity in weighted graph I want to know how to calculate the eccentricity of a vertex in a **weighted** graph, I know that when ever we talk about weighted graph if we want to calculate any distance we consi...
The usual definition of eccentricity of a vertex $v$ in an **unweighted** graph $G$ is the maximum over all distance from $v$ to vertices $w\in G$. Now define the eccentricity of a vertex $v$ as $$e_G(v)=\max_w d_G(v,w).$$ Not sure how widespread the use of this definition is but it seems to be a
