Discrete Mathematics and Its Applications

Product Information

In discrete calculus and the calculus of finite differences, a function defined on an interval of the integers is usually called a sequence. A sequence could be a finite sequence from a data source or an infinite sequence from a discrete dynamical system. Such a discrete function could be defined explicitly by a list (if its domain is finite), or by a formula for its general term, or it could be given implicitly by a recurrence relation or difference equation. Difference equations are similar to differential equations, but replace differentiation by taking the difference between adjacent terms; they can be used to approximate differential equations or (more often) studied in their own right. Many questions and methods concerning differential equations have counterparts for difference equations. For instance, where there are integral transforms in harmonic analysis for studying continuous functions or analogue signals, there are discrete transforms for discrete functions or digital signals. As well as discrete metric spaces, there are more general discrete topological spaces, finite metric spaces, finite topological spaces.

Return to footnote 2 reference in main content In addition to these foundational topics, an online discrete mathematics course often covers algorithms and data structures. Algorithms are step-by-step instructions that can be applied to solve problems. And data structures are ways of organizing data so that algorithms can be used effectively. Other computer science topics can include the design and analysis of algorithms, automata theory, and computability theory. Main article: Graph theory Graph theory has close links to group theory.

The time scale calculus is a unification of the theory of difference equations with that of differential equations, which has applications to fields requiring simultaneous modelling of discrete and continuous data. Another way of modeling such a situation is the notion of hybrid dynamical systems. What is Combinatorics? Open link in a new tab (2016). Oxford University Press Blog. Retrieved February 17, 2023. Return to footnote 4 reference in main content Theoretical computer science includes areas of discrete mathematics relevant to computing. It draws heavily on graph theory and mathematical logic. Included within theoretical computer science is the study of algorithms and data structures. Computability studies what can be computed in principle, and has close ties to logic, while complexity studies the time, space, and other resources taken by computations. Automata theory and formal language theory are closely related to computability. Petri nets and process algebras are used to model computer systems, and methods from discrete mathematics are used in analyzing VLSI electronic circuits. Computational geometry applies algorithms to geometrical problems and representations of geometrical objects, while computer image analysis applies them to representations of images. Theoretical computer science also includes the study of various continuous computational topics. Logical formulas are discrete structures, as are proofs, which form finite trees [10] or, more generally, directed acyclic graph structures [11] [12] (with each inference step combining one or more premise branches to give a single conclusion). The truth values of logical formulas usually form a finite set, generally restricted to two values: true and false, but logic can also be continuous-valued, e.g., fuzzy logic. Concepts such as infinite proof trees or infinite derivation trees have also been studied, [13] e.g. infinitary logic. Discrete mathematics is a critical component of computer science, so aspiring computer scientists need to understand its basics. Footnote 6 By understanding discrete mathematics and its applications, computer scientists can develop software applications, create networks, and develop algorithms to solve modern-day problems.Logic: includes basic propositional and predicate logic, as well as more complex topics like modal logic and the study of paradoxes.

Partition theory studies various enumeration and asymptotic problems related to integer partitions, and is closely related to q-series, special functions and orthogonal polynomials. Originally a part of number theory and analysis, partition theory is now considered a part of combinatorics or an independent field. Topological combinatorics concerns the use of techniques from topology and algebraic topology/ combinatorial topology in combinatorics.
