Number Theory
The field of number theory researches various types of mathematical subjects directly and indirectly related to numbers. Specifically, it researches algebraic manifolds, motifs and automorphic forms and representations, associated Galois representations and zeta and Lfunctions, and the special values, multiple zeta values, periods, ideal class groups, algebraic cycles, and Kgroups of those functions. Similarities between subjects in number theory and those in topology (especially knot theory) are also researched. Algebraic, geometric, and analytical methodologies are all used in number theory, which also has a deep relationship with representation theory. Computers can be actively used in this field.
