Ramanujan's Notebooks

This ebook constitutes the 5th and ultimate quantity to set up the implications claimed by means of the nice Indian mathematician Srinivasa Ramanujan in his "Notebooks" first released in 1957. even though all of the 5 volumes comprises many deep effects, might be the common intensity during this quantity is larger than within the first 4.

Problem-Solving and Selected Topics in Number Theory: In the Spirit of the Mathematical Olympiads

This ebook is designed to introduce the most vital theorems and effects from quantity idea whereas trying out the reader’s realizing via conscientiously chosen Olympiad-caliber difficulties. those difficulties and their options give you the reader with a chance to sharpen their abilities and to use the idea.

Primality testing for beginners

How are you going to inform no matter if a host is fundamental? What if the quantity has enormous quantities or hundreds of thousands of digits? this question could appear summary or inappropriate, yet actually, primality checks are played whenever we make a safe on-line transaction. In 2002, Agrawal, Kayal, and Saxena replied a long-standing open query during this context by way of providing a deterministic attempt (the AKS set of rules) with polynomial working time that tests even if a host is key or now not.
