ABSTRACT
This book began with the discussion of Fermat's Last Theorem and it is appropriate to end it with the news that FLT is now a proven theorem, thanks to the work of numerous mathematicians. The strategy for this proof was suggested by G. Frey [17]. Based on some heuristic arguments, he concluded that if FLT is false for an odd prime ℓ > 5 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003177036/f0af01d0-3a24-4c34-9b44-c23e4a0fe932/content/math11_1.tif"/> , i.e. if a ℓ + b ℓ = c ℓ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003177036/f0af01d0-3a24-4c34-9b44-c23e4a0fe932/content/math11_2.tif"/>
