If you are a math lover who wants to explore the deeper and more abstract aspects of mathematics, you might have heard of algebra abstracta. Algebra abstracta, also known as abstract algebra, is a branch of mathematics that studies algebraic structures such as groups, rings, fields, modules, vector spaces, lattices, and more. These structures are used to generalize and unify various concepts and operations from other areas of mathematics, such as arithmetic, geometry, number theory, cryptography, coding theory, etc.

## The Basics of Algebra Abstracta

Before we dive into the details of how to get John Fraleigh's book for free, let's review some of the basics of algebra abstracta. Algebra abstracta is not like the algebra you learned in high school or college. It is not about solving equations or manipulating expressions with variables. It is about studying the properties and patterns of different kinds of mathematical objects that can be defined by sets and operations.

A set is a collection of elements that share some common characteristics. For example, the set of natural numbers 1, 2, 3,... or the set of letters A, B, C,.... An operation is a rule that combines two or more elements from a set to produce another element from the same set. For example, addition (+) or multiplication (x) are operations on the set of natural numbers.

An algebraic structure is a set with one or more operations that satisfy certain conditions or axioms. For example, a group is an algebraic structure that consists of a set and one operation, usually called the group operation, that satisfies four axioms: closure, associativity, identity, and inverse. A ring is an algebraic structure that consists of a set and two operations, usually called addition and multiplication, that satisfy nine axioms: closure, associativity, commutativity, identity, inverse, distributivity, and zero. A field is an algebraic structure that consists of a set and two operations, usually called addition and multiplication, that satisfy all the axioms of a ring plus one more: multiplicative inverse.

These are just some examples of the many types of algebraic structures that algebra abstracta studies. Each type of structure has its own properties, theorems, and applications. For example, groups are used to study symmetry, permutations, rotations, cryptography, etc. Rings are used to study polynomials, matrices, modular arithmetic, coding theory, etc. Fields are used to study fractions, rational numbers, complex numbers, vector spaces, etc.

One of the main goals of algebra abstracta is to classify and compare different algebraic structures based on their properties and relations. For example, we can say that a field is a special kind of ring that has more properties than a general ring. We can also say that two groups are isomorphic if they have the same structure but different elements. We can also define substructures, homomorphisms, quotient structures, direct products, and other concepts that help us understand the similarities and differences between various algebraic structures.

To learn algebra abstracta, you need to be familiar with some basic concepts and tools from logic, set theory, proof techniques, and mathematical notation. You also need to be able to think abstractly and creatively about mathematical objects and their properties. You need to be able to use symbols and notation to express general ideas and patterns that apply to many different cases. You also need to be able to solve problems and prove statements using logical arguments and examples.

Here are some examples of algebra abstracta problems and solutions:

Problem

Solution

Show that the set Z6 = 0, 1, 2, 3, 4, 5 with the operation +6 defined as x +6 y = (x + y) mod 6 is a group.

We need to check the four axioms of a group:

- Closure: For any x, y in Z6, x +6 y is also in Z6, since (x + y) mod 6 is always between 0 and 5.

- Associativity: For any x, y, z in Z6, (x +6 y) +6 z = x +6 (y +6 z), since both sides are equal to (x + y + z) mod 6.

- Identity: There exists an element 0 in Z6 such that for any x in Z6, x +6 0 = 0 +6 x = x.

- Inverse: For any x in Z6, there exists an element -x in Z6 such that x +6 (-x) = (-x) +6 x = 0. We can find -x by subtracting x from 6 and taking the remainder mod 6.

Therefore, Z6 with +6 is a group.

Show that the set R[x] of all polynomials with real coefficients with the usual operations of addition and multiplication is a ring.

We need to check the nine axioms of a ring:

- Closure: For any p(x), q(x) in R[x], p(x) + q(x) and p(x) * q(x) are also in R[x], since adding or multiplying two polynomials with real coefficients results in another polynomial with real coefficients.
