This website
is – you guessed it! – “under construction” but in due time you’ll find here
practically all my published and unpublished papers. These are for the most part in mathematics
because – you guessed correctly again! – I am mostly a mathematician, but there
are some exceptions. Just as a sample,
here is one from long ago in which I had proved A Trace Formula,
and here is a later more whimsical paper of mine which points out and discusses
this Paradox
: the usual way in which Fluid Mechanics is taught “proves” that the
fundamental group of a circle is trivial!
And here, finally, is a very recent photograph I took of my shoes as I
was doing mathematics in my brother’s beautiful garden in
My plan, basically, is to just
complete the attached incomplete List and upload all its
items. In the meantime, see also
www.geocities.com/sarkaria_2000 and
www.geocities.com/karanbirsarkaria, my previous websites (which too have
remained “under construction” only for a very long time, and shall now soon be
deconstructed).
Dr. J. S. Sarkaria’s Cactus Book is also now on this website.
Update of April 11, 2010. As I had so astutely – clap! clap! – foreseen,
this site is still “under construction” after so many months (and the geocities
links have been defunct for almost as many), but, as those fond of avidly
perusing this website have no doubt noticed, I have stuck to my basic plan,
though perhaps at a less than blistering pace.
Besides, starting today – a Happy Birthday to you too! – I’ve started
building up another list, of hard-to-find items by
other authors that I have liked over the years, which too will be treated,
basically, as per the same tried-and-tested (or is it slow-but-steady?) plan.
Update of April 11, 2011. Considering how much more material has
been added to it during the last year, this website is now no longer “under
construction” in a restricted sense, but then again, considering how much more
remains to be uploaded, and even more, how much more by way of new projects
I’ve in the pipeline, it seems it is destined to remain happily “under
construction” for my lifetime? Anyway,
one project of the latter kind which did make it during the previous year was
the, by now well-known, paper from which the above photo—which also serves as
an entry to a picture gallery!—is extracted.
Update of April 11, 2012. As
they say: the more things change, the more they (appear to) remain the same …
Update of April 11, 2013. Chugging along ... and a special word
of thanks for all those who have been giving help from far away ... indeed
today only I received a scanned pdf of those long seminar notes from 1993-94 on
Poincaré’s Analysis
Situs ... so these too are now available on this website.
Update of April 11, 2014. Clicking
on the above pic will tell you that walking around and around those garden
paths can lead one to do funny things ... and there is much else too that is
new in List ... but I’ll let you explore for yourself
and pick and choose what catches your fancy ...
Update of April 11, 2015. Funny how what I spent almost all of this twelvemonth doing ... very little
of that got posted ... while a couple of btw things that
happened jlt did ... still, this little
should suffice to give, to at least some of you, a pretty good idea of what’s
cooking ...
Update of April 11, 2016. The trivial -- but crucial ! -- first
paragraph of PG&R had set the above ball rolling three years ago ...
besides, to answer some interesting questions that have arisen in its sequels,
I’ve been playing with arguments like the one below which uses a bricklaying
pattern.
Update of April 11, 2017. Time flew thanks to aliens who can go back in time
and some notes on
a footnote.
Update of April 11, 2018. “So what is your best work?” Never an easy question to answer, but
I’d say what I’ve done after 2009, especially Plain Geometry & Relativity, I-II-III-IV-V,
together with its burgeoning off-shoot, a topological reworking of
algebra. For the
manifesto of the latter click on the
first picture below, and for some related rubaiyaan (!) inspired by the
prettiest composition of Khayyam on the second. All translations are also
available from List, except of the latest installment posted today, of which the translation
will be made available as soon as it is ready.
Update
of April 11, 2019. It’s all
revolving now, around what Baby Algebra is proving in the picture below, as the
next and yet-to-be-translated part four
posted today further shows.
Update
of April 11, 2020. The picture
below of an hero of mine clicks to a miscellany of fifty thoughts, the
one-sided halo of the cake to the translation of part four, and posted now is
the yet-to-be-translated part five.
Update of
Update of April 11, 2022. Frolicking in the garden of mathematical delights, this
orbit found me mostly musing on elves from the eighties and nineties, and there
is lotta stuff from the past now added to List, but
there is much more on my to-do list that needs to be done ... however, at least
the following – my take on a wonderful but ‘secret’ place at a stone’s throw
almost from where we live! – I’ve now duly ticked off :-
Update of
Update of
Update of April 11,
2025. A pleasant connection was made this year between what
I am doing, and what I had discovered sixty years ago.
Which lifted nicely to a curious arithmetic that an imaginative primary school
student could have discovered, and indeed did in my opinion, and that
too not far from where I live! Also I discovered that that early discovery of
continuous but never differentiable motion by a brave bohemian—a heroic species
of mathematicians which later was even fashionable for a little while in the
free world, but alas has again dwindled to extinction in these terrible
times—was tied intimately to a lesser known, and decidedly more pacific,
version of the fable about the hare and the tortoise, in which the two are good
friends and tie their race, even though the former is always running
twice as fast as his pal:-
Back in the day then, mathematics too
was more heroic, and most of it still coming out in other European languages.
It is a no-brainer that (like poetry) a creative pursuit like mathematics is
pursued best in one’s own mother tongue, and especially with translation
between some languages already much easier now, I see no reason (outside those
belonging to the “business of mathematics”) why we mathematicians (again to be
distinguished from “mathematicians” who
alas are even more abundant now) should not do exactly that! Anyway, you’ll
again find added to List some more items in my mother
tongue, of which the one written jointly I particularly like; but this time
I’ve also posted translations of some beautiful short papers by others; and oh
yes, there is there now, rather late in the day, my very first paper in German!
