This page serves as the root for all documents in my directories, but only a small attempt has been made to make it fancy. Few special features are used to avoid shutting out those using older browsers.
Here is another picture taken by C. J. Mozzochi at the Workshop on Combinatorial and Additive Number Theory in May 2004.
I am a Professor in the Mathematics Department of the New Brunswick/Piscataway Campus of Rutgers University.
From 1991 to 1995, I was editor of the Problems and Solutions section of the American Mathematical Monthly.
I also belong to the TeX Users Group. At the meeting in August 2001, I learned about some amazing things that can be created in TeX for viewing in the PDF format. If you have version 4 (or newer) of the Acrobat Reader (version 3 won't work since a javascript interface is used), take a look at this calculator.
I was a fellow of Livingston College and represented the College on the New Brunswick Faculty Council. This has been compounded in two ways: (1) I became Faculty Council webmaster for the 2003-2004 academic year and continue in that role; (2) I was chair of the Livingston College Executive Council of Fellows for the 2005-2006 and 2006-2007 academic years. While Livingston College no longer has an Assembly of Fellows following the reorganization of the New Brunswick/Piscataway Campus, I remain of the Faculty Council as a representative of the Livingston Campus Community for 2007-2008. I was also elected to represent SAS on the University Senate for a 3 year term starting Fall 2007.
Because this page has gotten so top-heavy, a shortcut to student information has been added.
As department computer
coordinator, I am prepared to assist members of the department with
all computer-related questions. Office hours may be used to discuss
these questions. I have started a file of hints on computer use
that is evolving into a full-fledged FAQ file, and is now also
linked to the Department computing page
with the title Helpful hints for Math systems. A new addition
to our system is jsMath. Here is a sample page illustrating its abilities.
As part of a study of software to be added to our system, I have a collection of screen shots from my home system showing the effect of 3D widgets on programs that we use (or should use). As the image (stolen from the home page of a program that allows me to cope with people who can only write with a word processor) suggests, my support is limited to the systems I use: Solaris, linux and OS/2.
When results obtained at Rutgers are seen to apply elsewhere, they will be shared. Here is a modification of an article entitled How to listen to a maths lecture posted by T. W. Körner of the University of Cambridge. I changed the fonts changed to Times, but the original A4 paper size was retained.
As suggested by the image (stolen from a site devoted to
web design), I look forward to the day when I can user newer W3
standards on the pages that I maintain. In addition to this page, I
serve as webmaster for the Faculty Council and maintain several pages
for courses in the mathematics department. Style sheets are under
development to make it easier to produce pages that adhere to a small
number of standard formats.
Will Stein has provided web-based access to various computer algebra systems through his system called Software for Algebra and Geometry Experimentation. An earlier announcement claimed that it was for the benefit of those who needed to do algebraic computations on the Paris Metro, but it also works from Rutgers.
SASTRA University, a private university in South India formed about 15 years ago, has announced the SASTRA Ramanujan Prize of $10,000 to be awarded annually to a young mathematician not exceeding the age of 32 for outstanding contributions in an area of mathematics influenced by Ramanujan. Here is the full announcement.
Slides from a talk given in the New York Number Theory seminar and the Logic and Games seminar at the CUNY graduate Center in March 2006. The talk was based on my paper with Erik Ellentuck, "Finitely additive measures and the first digit problem" that appeared Fundamenta Mathematicae 65 (1969).
Slides from a talk in the AMS Special Session on Continued Fractions in January 2006, and later at the New York Number Theory seminar. entitled "Resurrecting the divided cell algorithm for inhomogeneous Diophantine approximation". (joint work with Mary Flahive). A revised version was presented at a conference in Japan in March 2007. It was then prepared for publication in the proceedings of the conference with the title "The divided cell algorithm and the inhomogeneous Lagrange and Markoff spectra". Here is a preprint
An article entitled Hand computation of matrix exponentials, based on some course notes is in a form that can be shown, although I intend further revision before submitting it for publication.
There is now a posted version of Sums of four squares from Number Theory: New York Seminar 1991-1995 (ISBN 0-387-94826-0).
A copy of Computing Endpoints in Markoff Spectra from number theory with an emphasis on the Markoff spectrum (ISBN 0-8247-8902-4) has been located, but minor reformatting will be required for posting.
Earlier publications are unlikely to be available. However, the following short papers were scanned.
I have participated in the New York Number Theory Seminar since its founding in 1982.
| Course and Section | Course Title | Meets | Time | Room | Campus | Final exam date time and place |
|---|---|---|---|---|---|---|
| 642:550:E6 | Linear Algebra and its Applications | MTTh | 6:00 - 8:30 PM | HLL-425 | (Busch) | Thursday, July 31 6 - 9PM, HLL-425 |
Scheduled office hours are valid only while classes are in session, but they are drop-in office hours -- no appointment is necessary. In addition, I am frequently available at other times. If scheduled times are not convenient and you don't find me in my office, appointments can be made. E-mail and telephone messages are checked regularly.
Office phone (in Hill 438) (USA)-732-445-0277. This is a private line with an answering machine, but it is much less reliable than e-mail for transmitting precise information. If you need a response, please sent e-mail.
Any links to current course material are in that section of the page. They usually point to a special page for my section. Other archives can be generally located by selecting "Course Materials" from the Mathematics Department Home Page, and following links to the appropriate course and section. Here are links to my archived material.
Material more than five years old will be removed unless it has some unique feature. Direct links to more recent material will also be removed if it can be reached through a more recent version of the same course.
