My area of research is Numerical Analysis and Scientific Computing. Click on
``Research'' below for more details. Syllabi and information on homework for
the courses that I am presently teaching can be found under ``Teaching.''
Links to software, software manuals, newsletters, professional societies, etc.,
can be found under ``Links.''
One of my professional interests is the development of the electronic medium
for scientific publication. We started the first electronic journal in
mathematics, ``Electronic Transactions on Numerical Analysis''
(ETNA), at Kent State University in
1993. Papers submitted for publication in ETNA are refereed just like papers
submitted to traditional commercial journals. However, differently from
commercial journals, access to papers published in ETNA is free. Other
advantages of ETNA include
there are no annual page limitations,
forward referencing,
interactive numerical experiments.
The latter feature is presently being developed for ETNA. Authors can append
an interface that allows a reader of the paper to carry out numerical experiments
of his/her own choice. In this way a reader can gain additional insight into
the performance of algorithms, sharpness of bounds, etc. See the interactive
supplements for the papers ``Fast Leja points'' by J. Baglama et al. in volume 7
of ETNA and ``On Gershgorin-type problems and ovals of Cassini'' by R. S. Varga
and A. Krautstengl in volume 8 of ETNA for illustrations.
