Study Notes
Discrete Structures
- Discrete mathematics is a branch of mathematics that deals with distinct or separate objects, like integers, sets, and propositions.
Theoretical Computer Science
- Theoretical computer science is a field that relies heavily on logic and graph theory.
- It helps analyze algorithms and their complexity (time taken to execute).
- The study of computability investigates what can be computed based on principles of formal language theory and automata theory.
Information Theory
- Information theory quantifies information by studying coding and data transmission.
- It focuses on designing efficient and reliable data storage and transmission methods.
Mathematical Logic
- Also known as formal logic, it analyzes principles of reasoning and valid inferences.
- Studies concepts like consistency, completeness, and soundness of logical systems.
- Explores mathematical proofs.
Set Theory
- Studies sets which are collections of objects, like prime numbers or colours.
- Examines relationships between sets, including partially ordered sets.
- Focuses on countable sets, including finite sets.
Combinatorics
- Explores ways to arrange and combine discrete structures.
- Enumerative combinatorics focuses on counting the number of combinatorial objects, such as combinations, permutations, and partitions.
- Analytic combinatorics uses tools from probability theory and complex analysis to study the enumeration of combinatorial structures.
Graph Theory
- A part of combinatorics that analyzes networks and graphs, with applications in various fields.
- Graphs represent relationships and structures found in both natural and man-made systems.
- Allows for the modelling and analysis of dynamics in social, biological, and physical systems.
Discrete Probability Theory
- Deals with events occurring in countable sample spaces.
- Useful for analyzing situations involving discrete events, like counting the number of birds in a flock.
- In contrast to continuous probability distributions, discrete probability doesn't deal with real numbers but with countable values.
Matrices
- Matrices are represented by uppercase letters.
- Elements in a matrix are denoted by lower case letters with two subscripts indicating their position in the row and column.
- For example, 'aij' represents the element in the ith row and jth column of matrix A.
Matrix Operations
- Matrices can undergo various operations like addition, subtraction, multiplication, and transposition.
Addition of Matrices
- Addition is only possible for matrices with the same number of rows and columns.
- Corresponding elements of the matrices are added together.
Subtraction of Matrices
- Subtraction is also only possible for matrices with the same number of rows and columns.
- Corresponding elements of the matrices are subtracted.
Scalar Multiplication
- Multiplying a matrix by a scalar 'c' involves multiplying each element of the matrix by 'c'.
Multiplication of Matrices
- Matrix multiplication only works if the number of columns in the first matrix is equal to the number of rows in the second matrix.
- The product of two matrices involves multiplying each row vector of the first matrix with each column vector of the second matrix.
Transpose of Matrices
- The transpose of a matrix is obtained by swapping rows for columns and vice versa.
Boolean Algebra
- Boolean algebra is a system of algebra that deals with only two possible values: 1 (true) and 0 (false).
- Introduced by George Boole in the 19th century as a way to simplify and analyze logical reasoning.
- Boolean algebra is crucial for digital circuits and computer science.
Boolean Arithmetic
- In Boolean arithmetic, the addition operation is represented as the logical "OR" operation.
- The sum of 1 + 1 is equal to 1 in Boolean algebra.
- Subtraction is not defined in Boolean algebra.
- The addition and subtraction of Boolean values follow the same logic as the truth table for the OR gate.
