Difference Equations

Applications of Lie Groups to Difference Equations

Vladimir Dorodnitzy Chapman & Hall/ CRC, 2010, 344 pp. The invariance of differential equations under transformation groups, usually Lie groups, naturally comes from the models they formalise, and there is a lot of literature dedicated to applications of Lie groups in differential equations. The difference schemes for solving differential equations, on

The Tangled Origins of the Leibnizian Calculus

Richard C Brown World Scientific, 2012, xxi+310 pp. As the title of the book suggests, this book attempts to unravel the threads that lead to the creation of the revolutionary symbolism of differential and integral calculus by the polymath Gottfried Wilheim Leibniz (1646–1716). We are all aware that

The Number of Solutions of a System of Linear Equations

The standard form of a linear equation in $$n$$ unknowns $$x_1,x_2,\dots ,x_n$$ is $$a_1x_1+a_2x_2+\dots +a_nx_n=b,$$ where $$a_1,a_2,\dots ,a_n$$ and $$b$$ are constants. Here constants mean some real numbers (these constants may

If p is a prime then √p is irrational

If p is a prime then √p is irrational

To prove √p is irrational, where p is a prime, we will need the following theorem: Theorem: If $$p$$ is prime then $$p|ab,$$ then $$p|a$$ or $$p|b.$$ Proof: If $$p|a,$$ we are done. So let us assume that $$pmid a.$$ Therefore, $$gcd(p,a)=1.$$ Hence,

Deligne wins Abel Prize 2013

This year’s Abel Prize has been awarded to the Belgian mathematician Pierre Deligne for “seminal contributions to algebraic geometry and for their transformative impact on number theory, representation theory, and related fields”. The Abel Prize was established in 2003 in memory of the Norwegian mathematician Niels Henrik Abel. It’

Pi Day

Pi Day is an annual celebration commemorating the mathematical constant π (pi). Pi Day is observed on March 14 (or 3/14 in month/day date format), since 3, 1 and 4 are the three most significant digits of π in the decimal form. In 2009, the United States House
