U+1D45E MATHEMATICAL ITALIC SMALL Q

U+1D45E was added to Unicode in version 3.1 (2001). It belongs to the block U+1D400 to U+1D7FF Mathematical Alphanumeric Symbols in the U+10000 to U+1FFFF Supplementary Multilingual Plane.

This character is a Lowercase Letter and is commonly used, that is, in no specific script.

The glyph is a Font composition of the glyph Latin Small Letter Q. It has a Neutral East Asian Width. In bidirectional context it acts as Left To Right and is not mirrored. The glyph can, under circumstances, be confused with 1 other glyphs. In text U+1D45E behaves as Alphabetic regarding line breaks. It has type Lower for sentence and Alphabetic Letter for word breaks. The Grapheme Cluster Break is Any.

The material conditional (also known as material implication) is an operation commonly used in logic. When the conditional symbol β {displaystyle ightarrow } is interpreted as material implication, a formula P β Q {displaystyle P ightarrow Q} is true unless P {displaystyle P} is true and Q {displaystyle Q} is false. Material implication can also be characterized inferentially by modus ponens, modus tollens, conditional proof, and classical reductio ad absurdum.

Material implication is used in all the basic systems of classical logic as well as some nonclassical logics. It is assumed as a model of correct conditional reasoning within mathematics and serves as the basis for commands in many programming languages. However, many logics replace material implication with other operators such as the strict conditional and the variably strict conditional. Due to the paradoxes of material implication and related problems, material implication is not generally considered a viable analysis of conditional sentences in natural language.
