Mathematical objects tend to have certain "certain types of links" to other concepts.

• Types: of functions (injections, surjections, etc.)
• Examples: of functions (worked problems, example of usage, etc.)
• Constructions: math objects constructed from the object (ex. related rates from derivation)
• Generalizations: abstractions (think of the bigger picture the topic comes from)
• Questions: questions about subject
• Properties: related properties
• Sufficiencies: requirements of another function/definition or required to know

For example, a note called Function.md, which defines a function would have links like:

• types of functions (injections, surjections, etc.),
• examples of functions (functions in a topological/metric space),
• constructions (image, preimage, compositions, etc.),
• generalizations (morphisms, relations, etc.),
• properties (collection of all functions form a proper class),
• sufficiencies (certain conditions that guarantee certain properties of functions, say 'criteria for equality of functions', or other set-theoretic stuff that guarantees the existence of a function...)
