Greeting
In the pure mathmatics, there are three research fields of the Algebra,
the Analysis and the Geometry mainly. In the geometry, there are three
fields of the differential geometry, the topology and the Algebraic Geometry.
The differential Geometry is the field researching the space (which is
called a manifold) where can treat the continuity and the differentiabiliy
of various geometric quanttities and researching the properties of the
figures in the space which are invariant under some Lie group action (on
the space). The topology is the field researching the space (which is called
a topological space) where can treat only the continuity of various quantities
and researching the properties of the figures in the space which are invariant
under continuous deformations. The algebraic geometry is the field researching
the properties of the figures given as the common zero-point set of some
polynomials. The purpose of this division of research is to construct the
comprehensive geometric theory of the natural science (in wide sense) of
the quantum mechanics, the condense matter theory, molecular biology, the
grain boundary structure theory and composite materials mechanics, and
feedback to each of the above fields of the natural science. This division
was started from April 1st in 2025 for the above purpose.
