पाटीगणित (श्रीधराचार्य - प्राचीन संस्कृत टीका एवं प्रो. कृपाशंकर शुक्ल सविस्तार व्याख्या)

ii INTRODUCTION
copy of that manuscript. When the copy was received and
examined, his conjecture came out to be true. The occur-
rence in the manuscript of the verses which were ascribed
by the later writers to Śrīdharâcârya’s Pâtīgaṇita proved
beyond doubt that it was the manuscript of the very same
work. This is how the manuscript of the present work was
discovered.
Soon after the discovery of this important manuscript,
I joined Dr. Singh in his researches on Hindu Mathematics.
Both of us felt the necessity of publishing this manuscript, but
as the manuscript was incomplete and suffered from errors
and inaccuracies, it was considered advisable to wait for some
time for the discovery of another complete and better manu-
script. We waited, but inspite of our best efforts in this
direction another manuscript could not be traced. We there-
fore decided to edit the available manuscript, however incom-
plete and defective it was. Due to other work in hand,
however, the task of editing this manuscript could not
be undertaken during the lifetime of Dr Singh. Although
the text of the manuscript was already studied by the present
editor during 1948-49 while helping Dr Sabal Singh of
Balwant Rajput College, Agra, in writing his thesis on
Śrīdharâcârya, the regular work of editing the manuscript
was started only in July, 1957.
We have seen above that the available manuscript is in-
complete. Let us now describe it more fully. It starts with
an invocation to God Gaṇeśa, Lord of Success, by the commen-
tator, and runs up to the twenty-third verse of the Kṣetra-
vyavahâra (‘Determinations pertaining to plain figures’). The
available portion of the work comprises the following topics :
(1) Definitions, (2) Logistics (parikarma), (3) Deter-
minations pertaining to mixtures of things (miśraka-vyavahâra),
(4) Determinations pertaining to series (śreḍhī-vyavahâra), and
(5) Determinations pertaining to plain figures (kṣetra-vyavahâra),
the last topic being incomplete.
