1 day ago · Robin J. Wilson is the leading writer in the field having published a well-reviewed [13] [14] [15] book entitled Stamping through mathematics in 2001, [1] a paper on European mathematical history through stamps, [16] and also contributing the Stamp Corner column to the The Mathematical Intelligencer starting in 1984.

1 day ago · The field of mathematics that studies sheaves is called sheaf theory. Sheaves are understood conceptually as general and abstract objects. Their correct definition is rather technical. They are specifically defined as sheaves of sets or as sheaves of rings, for example, depending on the type of data assigned to the open sets.
1 day ago · In mathematics, specifically group theory, the free product is an operation that takes two groups G and H and constructs a new group G ∗ H. The result contains both G and H as subgroups, is generated by the elements of these subgroups, and is the “universal” group having these properties, in the sense that any two homomorphisms from G and H into a group K factor uniquely through a ...
1 hour ago · Whether the multiplicative identity is to be preserved depends upon the definition of ring in use. If the multiplicative identity is not preserved, one has a rng homomorphism. A linear map is a homomorphism of vector spaces; that is, a group homomorphism between vector spaces that preserves the abelian group structure and scalar multiplication.
1 day ago · This means that there is a non-zero chance for the algorithm to succeed, so an embedding must exist. Attempting to directly embed all the vertices of in this manner does not work because the algorithm may get stuck when only a small number of vertices are left.
1 day ago · Particulars are individual entities and include both concrete objects, like Aristotle, the Eiffel Tower, or a specific apple, and abstract objects, like the number 2 or a specific set in mathematics. Also called individuals , [ e ] they are unique, non-repeatable entities and contrast with universals , like the color red, which can at the same time exist in several places and characterize ...
1 day ago · Analytic philosophy is a broad, contemporary movement or tradition within Western philosophy, especially anglophone philosophy, focused on analysis. [a] [b] Analytic philosophy is characterized by a clarity of prose; rigor in arguments; and making use of formal logic and mathematics, and, to a lesser degree, the natural sciences.
