An Overview of the Proof of Fermat’s Last Theorem

To prove the theorem we follow the program outlined by Serre in [16]. Fix a prime p 5 and suppose a,b,c 2 Z satisfy ap + bp + cp = 0 but abc 6= 0. The triple (ap,bp,cp) is what Gerhard Frey has called a “remark- able” triple of integers, so remarkable in fact, that we suspect it …

BASICS OF THE SPECTRUM ANALYZER - UC Santa Barbara

Fourier ⋅ π → − + + Now instead of a bank of narrow filters, we shall have one narrow filter centered at a fixed frequency, say fI, and we shall scan the signal spectrum across this filter by multiplying x(t) by a sinusoid of varying frequency f0. See Figure 1. …
