What it is Filled
Discrete mathematics is the field of mathematics concerned with discrete structures, including finite sets, integers, graphs and finite sequences, studied through methods such as logical proof, combinatorial counting and recursive construction.
In scope
- Discrete structures such as graphs, finite sequences, sets, relations, partially ordered sets and combinatorial configurations
- Questions of existence, enumeration, structure, extremal behaviour and discrete optimisation
- Proof techniques including induction, bijection, invariants, contradiction and combinatorial probabilistic arguments
- Relationships between mathematical results, constructive procedures and computational complexity
- Declared curricular, research and classification conventions that determine the field's boundaries
Out of scope
- Continuous analysis and differential equations as independent fields, while retaining their use in discrete problems
- The full scope of logic, number theory, algebra and probability beyond their identified discrete-mathematical contributions
- Software engineering and concrete implementations of algorithms
- Empirical application domains whose situations are represented using discrete structures
- Practitioners, departments, societies and publications as independently modelled people, organisations or information objects
Why it exists Filled
Enable an agent to recognise discrete mathematics as a field, assess the scope and justification of its knowledge, and select appropriate discrete representations and reasoning methods.
Distinguishing features Filled
- A problem centrally concerns distinguishable elements and combinatorial relationships, rather than merely using digitally stored numbers.
- The subject includes infinite discrete structures; finite size alone neither defines membership nor establishes the field's boundary.
- A contribution may establish existence, counting or structural properties without supplying an algorithm, distinguishing the field from a purely computational treatment.
- An application enters this model through its discrete abstraction and mathematical questions, rather than through the application domain's full empirical behaviour.
- Membership of neighbouring subjects such as logic or number theory is recorded against an explicit curricular or research convention, rather than assumed from the label alone.
What robots and AI may and may not do Filled
Must not
- Present a flawed or incomplete proof as correct.
- Complete assessed coursework for a student who is meant to do it alone.
- Attribute a theorem or result to the wrong person.
Only with a human decision
- Using a discrete model to make decisions about people, such as in scheduling or allocation.
May
- Teach and explain discrete mathematics topics, with correct proofs.
- Check counting, graph and logic arguments a user submits and point out errors.
Moral aspects Filled
- Discrete methods underpin cryptography and algorithms that decide outcomes for people, so errors spread widely.
Who is affected
- Students
- Users of software built on it
Owners Filled

Nobody owns it; it is held in common as mathematics.
