What is discrete mathematics and why is it important?




Discrete mathematics is the branch of mathematics that deals with finite or countable structures, such as sets, logic, relations, functions, combinatorics, graphs, algorithms, algebraic structures, and coding theory. Unlike continuous mathematics, which studies smooth and continuous phenomena, such as calculus and analysis, discrete mathematics focuses on discrete and discrete phenomena, such as integers, binary digits, truth values, permutations, trees, encryption schemes, etc.


Discrete mathematics is important because it provides the theoretical foundation for many fields of science and engineering, especially computer science and information technology. Discrete mathematics helps us to model and analyze various aspects of computation, such as data structures, algorithms, complexity, cryptography, artificial intelligence, logic programming, database systems, network protocols, coding theory, etc. Discrete mathematics also helps us to develop abstract thinking skills and logical reasoning abilities that are essential for solving problems and proving theorems.


Who is C.L. Liu and what are his contributions to discrete mathematics?




C.L. Liu (Chung Laung Liu) is a distinguished professor emeritus of computer science at the University of Illinois at Urbana-Champaign.

Relations and functions




The fifth chapter defines and explores the properties of relations, such as reflexivity, symmetry, transitivity, equivalence relations, partial orders, etc. The sixth chapter introduces the concept of functions and their types, such as one-to-one functions, onto functions, bijections, inverse functions, composition of functions, etc. The seventh chapter deals with some special functions and sequences that are important in discrete mathematics and computer science, such as factorial function, binomial coefficients, Fibonacci sequence, recurrence relations, generating functions, etc.


Combinatorics and recurrence relations




The eighth chapter studies the techniques and principles of counting and enumeration, such as the sum rule, the product rule, the inclusion-exclusion principle, permutations, combinations, arrangements, etc. The ninth chapter applies the counting techniques to various problems involving discrete probability and statistics, such as sample spaces, events, probability axioms and rules, conditional probability, Bayes' theorem, expected value, variance, standard deviation, etc. The tenth chapter revisits the topic of recurrence relations and shows how to solve them using different methods, such as iteration method, characteristic equation method, generating function method, etc.


Graph theory and algorithms




The eleventh chapter introduces the basic concepts and terminology of graph theory, such as graphs, vertices, edges, degrees, paths, cycles, connectedness, components, etc. The twelfth chapter explores some special types of graphs and their properties, such as trees, rooted trees, spanning trees, binary trees, Eulerian graphs, Hamiltonian graphs, planar graphs, etc. The thirteenth chapter discusses some algorithms and applications of graph theory in computer science and engineering, such as graph traversal algorithms (breadth-first search and depth-first search), shortest path algorithms (Dijkstra's algorithm and Floyd-Warshall algorithm), minimum spanning tree algorithms (Prim's algorithm and Kruskal's algorithm), network flow algorithms (Ford-Fulkerson algorithm and Edmonds-Karp algorithm), etc.


Algebraic structures and coding theory




The fourteenth chapter introduces the concept of algebraic structures and their examples in discrete mathematics and computer science, such as groups, subgroups, cyclic groups, permutation groups, cosets, normal subgroups, quotient groups, rings, subrings, ideals, quotient rings, fields, vector spaces, matrices, etc. The fifteenth chapter applies the algebraic structures to the field of coding theory, which deals with the design and analysis of codes for data transmission and storage, such as binary codes, Hamming distance, Hamming weight, error detection, error correction, linear codes, Hamming codes, cyclic codes, Reed-Solomon codes, etc.
