Theory of functions of a real variable.

In Chapter II I do the basics of Hilbert space theory, i.e. what I can do without measure theory or the Lebesgue integral. The hero here (and perhaps for the first half of the course) is the Riesz representation theorem. Included is the spectral theorem for …

A Mathematical Theory of Communication

J. W. Tukey. A device with two stable positions, such as a relay or a flip-flop circuit, can store one bit of information. N such devices can store N bits, since the total numberof possible states is 2N and log 2 2 N = N. If the base 10 is used the units may be called decimal digits. Since log2 M = log10 M log10 2 = 3: 32log10 M;

Group Theory and the Rubik's Cube

Again, we’re going to rewrite this using new symbols. Let mean multiplication, and let e= 1, a= 2, b= 4, and c= 3. Then, the multiplication table for (Z=5Z) looks like e a b c e e a b c a a b c e b b c e a c c e a b Notice that this is exactly the same as the table for addition on Z=4Z!

Unit 5: Change of Coordinates

B= S 1v. Theorem: If T(x) = Ax is a linear map and S is the matrix from a basis change, then B = S 1AS is the matrix of T in the new basis B. Proof. Let y = Ax. The statement [y] B= B[x] Bcan be written using the last theorem as S 1y = BS 1x so that y = SBS 1x. Combining with y = Ax, this gives B = S 1AS. 5.4. If two matrices A;B satisfy B = S ...

Lines and Planes in R3

Lines and Planes in R3 A line in R3 is determined by a point (a;b;c) on the line and a direction ~v that is parallel(1) to the line. The set of points on this line is given by fhx;y;zi= ha;b;ci+ t~v;t 2Rg This represents that we start at the point (a;b;c) and add all scalar multiples of the vector ~v.

Lecture 9: Partial derivatives

Lecture 9: Partial derivatives If f(x,y) is a function of two variables, then ∂ ∂x f(x,y) is defined as the derivative of the function g(x) = f(x,y), where y is considered a constant. It is called partial derivative of f with respect to x. The partial derivative with respect to y is defined similarly. We also use the short hand notation ...
