Homological algebra and representation theory form a powerful confluence in modern mathematics. Homological algebra provides a framework for analysing algebraic structures via chain complexes, ...

Determine if the following equation represents a function: ...

A partition of a positive integer n is a non-increasing sequence of positive integers whose sum is n, the partitions of 3 ...

For any fiat 2-category C, we show how its simple transitive 2-representations can be constructed using co-algebra 1-morphisms in the injective abelianization of C. Dually, we show that these can also ...

Under OS/390, floating-point representation (unlike scientific notation) uses a base of 16 rather than base 10. IBM mainframe systems all use the same floating-point representation, which is made up ...

is a numeric matrix or literal. is the number of decimal positions. The CHAR function takes a numeric matrix as an argument and, optionally, a field width w and a number of decimal positions d. The ...
