 Summary of Department of Mathematics at TMU (by Guest Martin)

The Division of Mathematical Sciences offers a comprehensive program in
mathematics (covering the basic fields of algebra, geometry, and analysis
together with their applications), as well as a program in mathematical
information science (focusing on discrete mathematics, computer languages,
and applications such as cryptography).  In addition to the collection of
the central library, the mathematics library has an extensive collection of
specialized books and journals.  Up to date computer facilities are also
maintained by the department.  This excellent study environment is supported
by a system of faculty office hours and a "math clinic" where students can
ask questions and receive advice.  Faculty members are active researchers in
their own fields, and all students have the opportunity to make contact with
current research problems in mathematics and information science by taking
part in seminars.
The training provided by these programs equips students for any career which
requires rigorous quantitative and conceptual analysis, or for further study
and research in graduate school.

The Department has 22 permanent faculty members, together with several
research assistants and short term visitors. There are generally around 65 
graduate students including several foreign students. The graduate program 
(master's course and doctoral course) is available for suitably qualified 
students who have completed their undergraduate (or master's course) studies;
entrance examinations for the master's course are offered in September and 
February, while those for the doctoral course are held in January. 
Current information on the faculty can be found at

Formally the faculty members are divided into three groups, corresponding to
Pure Mathematics, Applied Mathematics and Information Sciences, although in
practice the differences are blurred and cross-boundary work is encouraged. 
Students pursue their studies and research under the close supervision of a
faculty member, and must attend a program of lectures and seminars. The 
relatively small size of the Department permits a friendly and supportive
atmosphere. However, students have easy access to a very wide range of
research seminars and international conferences which are held frequently
at this and other universities in the Tokyo area. To provide a suitable
environment for high-level study and research, the Department has a very 
good library (34,000 books, 23,000 journal volumes, as well as electronic
subscriptions to most major journals) and excellent computer facilities. 
Scholarships are offered to most doctoral students and to selected 
students in the master's course. There is also a TA system which offers a
small amount of additional financial support. Graduates of the master's 
program have a very wide range of career opportunities in industry or 
the public sector; graduates of the doctoral course mainly go on to 
educational or research institutions or follow specialized careers such 
as mathematical finance. 

My Profile and Current Data

Research Fields: Topology and Geometry.  Various Geometric Structures on Manifolds.

 I am mainly interested in the space form problems invarinat under
transformation groups; 
(i) Actions on manifolds and representations of fundamental groups.
(ii) Geometric structures on manifolds, construction of geometric invariant
tensor and uniformization of its vanishing.More precisely, 
(1) Smooth (finite group) actions on homotopy spheres.
(2) Compact aspherical space form problems (Properly discontinuous actions of 
infinite groups on contractible manifolds, Smooth rigidity on compact smooth
aspherical manifolds.)
(3) Rigidity and global geometric flow on compact smooth manifolds;
Flat affine flow, Lorentz flow, Conformal flow, CR-flow, Quaternionic CR flow,
Locally conformal Kaehler flow. Complex contact flow.
