Amalgamation Or Coproduct Symbol
⨿ is the amalgamation or coproduct symbol used in mathematics.
U+2A3F
The symbol ⨿ is used in mathematical contexts to denote an amalgamation or coproduct. It’s helpful when writing about objects combined via a coproduct construction. Below you’ll find practical ways to copy and use it.
Amalgamation Or Coproduct Symbol Meaning
⨿ is the Unicode symbol named “AMALGAMATION OR COPRODUCT” (U+2A3F). In mathematics, it commonly represents a coproduct operation, i.e., a way to combine objects so that maps out of the combined object correspond to maps from each component. It is also used when expressing “amalgamation” ideas, depending on the author’s context and the structures being discussed. If you see ⨿ in typed math notation, it typically signals a categorical or algebraic construction rather than ordinary addition or union. Use it when your text or notation needs a clear, typographic symbol for coproduct-style combination.
Common uses
- •Writing notes or homework on category theory coproduct constructions
- •Denoting a coproduct of objects in formal math expressions
- •Labeling components in combinational structure diagrams in typesetting
- •Using the symbol in research writing to distinguish coproduct from union or sum
- •Including ⨿ in LaTeX/Unicode math documents for consistent typography
Examples
⨿ Amalgamation or Coproduct
- ⨿Let A ⨿ B be the coproduct of A and B.
- ⨿Maps from A ⨿ B correspond to pairs of maps from A and B.
- ⨿Define C as an amalgamation of two substructures using ⨿.
- ⨿We write X ⨿ Y for the combined object in the construction.
- ⨿In this section, ⨿ denotes the coproduct operation.

FAQ
What does the symbol ⨿ stand for?
⨿ is the Unicode symbol “AMALGAMATION OR COPRODUCT” (U+2A3F), commonly used to denote a coproduct-style combination in mathematics.
Where can I copy ⨿ for my writing or code?
Copy the character directly from this page. You can also use the HTML entity (⨿) or the escapes when your editor supports them.
How do I use ⨿ in code or text editors?
You can insert the character directly (⨿), or use the provided escapes: CSS escape \\2A3F or JavaScript escape \\u{2A3F}.
Is ⨿ the same as the union symbol or addition?
Not exactly. While it’s a “combining” notation, ⨿ specifically refers to amalgamation/coproduct structure, which is distinct from typical set union or ordinary arithmetic addition.
