U+2A7B "⩻" Less-than with Question Mark Above Unicode Character

U+2A7B "⩻" Less-than with Question Mark Above is a mathematical symbol that combines the standard less-than sign with a question mark placed directly above it, primarily used in formal logic and mathematics to denote a relation that is suspected or questioned to be one of less than, often within the context of uncertain or conjectural inequalities. It allows mathematicians to express a tentative comparison where the truth of the less-than relationship is not yet established but is being considered or hypothesized. This character is part of the Supplemental Mathematical Operators block in Unicode, providing a concise typographic solution for representing this nuanced relational concept in digital text and scholarly documents.
