DIFFERENTIATING UNDER THE INTEGRAL SIGN - Keith …

2 KEITH CONRAD If you are used to thinking mostly about functions with one variable, not two, keep in mind that (1.2) involves integrals and derivatives with respect to separate variables: integration with respect to xand di erentiation with respect to t. Example 1.2. We saw in Example1.1that R 1 0 (2x+t3)2 dx= 4=3+2t3 +t6, whose t-derivative ...

THE CHINESE REMAINDER THEOREM

The Chinese remainder theorem can be extended from two congruences to an arbitrary nite number of congruences, but we have to be careful about the way in which the moduli are relatively prime. Consider the three congruences x 1 mod 6; x 4 mod 10; x 7 mod 15:

KEITH CONRAD 1. Introduction The Miller{Rabin test is the most widely used probabilistic primality test. For odd composite n>1 over 75% of numbers from to 2 to n 1 are witnesses in the Miller{Rabin test for n. We will describe the test, prove the …

GALOIS THEORY AT WORK: CONCRETE EXAMPLES

GALOIS THEORY AT WORK: CONCRETE EXAMPLES 3 Remark 1.3. While Galois theory provides the most systematic method to nd intermedi-ate elds, it may be possible to argue in other ways. For example, suppose Q ˆFˆQ(4 p 2) with [F: Q] = 2. Then 4 p 2 has degree 2 over F. Since 4 p 2 is a root of X4 2, its minimal polynomial over Fhas to be a ...

The map t7!tpn is also additive since it’s the n-fold composite of t7!tp with itself and the composition. 4 KEITH CONRAD of homomorphisms is a homomorphism.2 The xed points of an additive map are a group

ORDERS OF ELEMENTS IN A GROUP Introduction

Theorem3.2gives a nice combinatorial interpretation of the order of g, when it is nite: the order of gis the size of the group hgi. In fact, this even works when ghas in nite order (then hgiis an in nite group), so the order of gis always the size of hgi. The nite order of an element is linked to periodicity in its powers, as follows. Theorem 3.4.

TENSOR PRODUCTS Introduction R e f i;j c e f

Tensor products rst arose for vector spaces, and this is the only setting where they occur in physics and engineering, so we’ll describe tensor products of vector spaces rst. Let V and W be vector spaces over a eld K, and choose bases fe igfor V and ff jgfor W. The tensor product V KWis de ned to be the K-vector space with a basis of formal ...

DIHEDRAL GROUPS Introduction - University of Connecticut

1. Introduction For n 3, the dihedral group D n is de ned as the rigid motions1 taking a regular n-gon back to itself, with the operation being composition. These polygons for n= 3;4, 5, and 6 are pictured below. The dotted lines are lines of re ection: re ecting the polygon across each line brings the polygon back to itself, so these re ...

lower integrals are also defined there and used in Section 3.2 to study the existence of the integral. Section 3.3 is devoted toproperties of the integral. Improper integrals are studied in Section 3.4. I believe that my treatment of improper integrals is more detailed than in most comparable textbooks.
