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
1992. Papers submitted for publication in ETNA are refereed just like papers
submitted to traditional professional journals. However, differently from
traditional journals, ETNA is published on the internet and on CDROMs, only.
These media of publication allow
faster publication than traditional journals, because there are no
annual page limitations,
interactive numerical experiments.
The latter feature is presently being developed for ETNA. Authors can append
an interface written in Java 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
