What it is Filled
A property that a mathematical object may have, expressed as a predicate or unary relation over a class of objects, such as continuity, differentiability, convexity or square-integrability of functions, geometric continuity of curves, stability properties of systems, and productive properties preserved under products in topology; the registry treats such properties as functions from objects to truth values.
Why it exists Filled
Let an agent explain mathematical properties as predicates, relay examples across analysis, topology and geometry from mathematics references, describe the properties the registry aliases name, and distinguish properties from structures, invariants, relations of higher arity and physical properties.

What robots and AI may and may not do Filled
Must not
- Claim a function or system has a property without proof or a cited source.
- Confuse a property with a structure or with a count such as degrees of freedom.
- Present a stability claim as certified when it has not been checked.
Only with a human decision
- Relying on a claimed property in a safety-critical design.
May
- Explain mathematical properties such as continuity or convexity, citing mathematical sources.
- State precisely the class of objects a property is defined on.
Moral aspects Filled
- Engineers rely on properties such as stability; unchecked claims can cause failures.
- Mathematical errors in teaching propagate to students.
Who is affected
- Students
- Engineers relying on proofs

Recognition optional Filled
- A mathematical property is a predicate that mathematical objects may satisfy.
- Examples include stability, square-integrability, productive properties and geometric continuity, while degrees of freedom is a count rather than a truth-valued property.
- Structures add operations, invariants are preserved quantities, relations may relate several objects, and physical properties are measured.
- Not a visible object; a predicate.
Capabilities and actions required Filled
- explain the concept
- relay examples
- describe named properties
- distinguish related concepts
Hazards and failure modes required Filled
- Confusing properties with structures
- Registry aliases mixing properties and counts
- Vagueness of the general notion
Standards and interfaces required Filled
- No regulation
Context of use required Filled
- Not applicable; a mathematical concept.
- analytic properties such as continuity and square-integrability
- topological properties including productive properties
- geometric properties such as geometric continuity
- dynamical properties such as stability
- counting notions such as degrees of freedom
- unary relations in logic

Open questions
- Should the named properties be separate primary entries?
- How should mathematics references be linked?
- The registry alias degree of freedom is a count rather than a property; should it be split off?
