Here you can find some recent works of mine (up to about 10 years old work).
If work has not been published,
the date next to the title is the latest date of modification of the work
(usually, the date of submission).
If the work has been published, you should always get the published version,
as it is usually more accurate than the one posted here.
These preprints are provided to you "as they are," and are not guaranteed to be
mistake free. If you find any, I will appreciate hearing about it. In fact,
please feel free to send me your comments on these works.
Finally, please avoid plagiarizing these works, and please quote
them in any work of yours which make use of them. Thanks. LD.
