X. Major contributions:
Goldbach’s conjecture:
• One of the important illustrations of Ramanujan contribution towards the proof of the conjecture
• The statement is “every even integer greater than 2 is the sum of two primes”
i.e.; 6 =3 + 3
• Ramanujan and his associates had shown that every large integer could be written as the sum of at most 4 eve; 43=2+5+17+19
Partition of whole numbers:
• Ramanujan developed a formula for the partition of any number which can be made to yield the record result by a series of successive approximation
• Example: 3=3+0= 1+2= 1+1+1
Ramanujan number:
• 1729 is a famous Ramanujan number:
• It is the smaller number which can be expressed as the sum of 2 cubes in two different ways
• 1729=13+123=93+103
