Does Not Force Symbol
⊮ is the “does not force” symbol, used to express a non-implication or the absence of forcing.
U+22AE
The symbol ⊮ is commonly read as “does not force.” It appears in mathematical notation where authors want to state that a forcing relation does not hold.
Does Not Force Symbol Meaning
⊮ is the “does not force” mathematical symbol (Unicode name: “DOES NOT FORCE”, code point U+22AE). In practice, it’s used to indicate that one condition does not force another, often in contexts related to logic, set theory, or forcing-like formalisms. When writing formulas, it helps distinguish between a positive forcing relation and its negation, making the logical intent explicit. If you’re typesetting math, using the correct Unicode character ensures consistent rendering across editors that support it.
Common uses
- •Negating a forcing relation in mathematical or logical statements
- •Writing notes or comments in drafts where one condition is explicitly not forcing another
- •Annotating proofs or definitions with a clear “does not hold” forcing step
- •Marking non-implication in logic-heavy documents and lecture slides
- •Including the symbol in technical writing where Unicode math consistency matters
Examples
⊮ Does Not Force Symbol
- ⊮Condition A ⊮ Condition B, so the next step cannot proceed.
- ⊮The hypothesis implies not( A forces B ), written as A ⊮ B.
- ⊮In this model, the chosen partial order gives ⊮ rather than a forcing relation.
- ⊮We state that p ⊮ ϕ to indicate the required forcing fails.
- ⊮For readability, the author uses ⊮ to show the negated forcing claim.
