# Electron in the initial state is represented by a solid line with an arrow pointing toward the vertex (→•).

# Electron in the final state is represented by a line with an arrow pointing away from the vertex: (•→).

# Positron in the initial state is represented by a solid line with an arrow pointing away from the vertex: (←•).

# Positron in the final state is represented by a line with an arrow pointing toward the vertex: (•←).

# Each integration coordinate is represented by a point ( sometimes called a vertex );

# First, analysis to determine structural properties of a network, such as the distribution of vertex degrees and the diameter of the graph.

# Convert the Eulerian circuit of into a Hamiltonian cycle of in the following way: walk along, and each time you are about to come into an already visited vertex, skip it and try to go to the next one ( along ).

# stand on an arbitrary vertex as current vertex.

# find out the shortest edge connecting current vertex and an unvisited vertex V.

# set current vertex to V.

# Input Assembler: Reads in vertex data from an application supplied vertex buffer and feeds them down the pipeline.

# Vertex Shader: Performs operations on a single vertex at a time, such as transformations, skinning, or lighting.

# Domain Shader: Performs operations on vertices output by the tessellation stage, in much the same way as a vertex shader.

# Maekawa's theorem: at any vertex the number of valley and mountain folds always differ by two in either direction

# Kawasaki's theorem: at any vertex, the sum of all the odd angles adds up to 180 degrees, as do the even.

# The altitude of a triangle, which is the length from a vertex of a triangle to the line formed by the opposite side ;

# In an isosceles triangle, if the ratio of the base angle to the angle at the vertex is algebraic but not rational, is then the ratio between base and side always transcendental?

# Edges connecting an interior and exterior vertex.

# Each vertex on an edge of ABC is to be colored only with one of the two colors of the ends of its edge.

# A vertex algebra V is constructed that is a graded algebra affording the moonshine representations on M, and it is verified that the monster module has a vertex algebra structure invariant under the action of M. V is thus called the monster vertex algebra.

His lengthiest interview was featured as the cover story in The Comics Journal # 127 in the late 1980s.

These longer strips include The Bash Street Kids Adventures written and drawn by Kev F Sutherland which since 2004 have featured parodies of famous comic strip images, including Amazing Fantasy's first Spider-Man cover, Action Comics ' first Superman cover, and most recently the cover of X Men # 100.

# X has a sub-base such that every cover of the space by members of the sub-base has a finite subcover ( Alexander's sub-base theorem )

# Every open cover of A has a finite subcover.

These skillfully rendered paintings encouraged fan Glenn Bray to ask Barks if he could commission a painting of the ducks (" A Tall Ship and a Star to Steer Her By ", taken from the cover of Walt Disney's Comics and Stories # 108 by Barks ).

# Wildlife: stream improvement, fish stocking, food and cover planting

The company's second title, New Comics # 1 ( cover date December 1934 ), appeared in a size close to what would become comic books ' standard during the period fans and historians call the Golden Age of Comic Books, with slightly larger dimensions than today's.

# Evergreen needleleaf forest – Natural forest with > 30 % canopy cover, in which the canopy is predominantly (> 75 %) needleleaf and evergreen.
