What does the function f: x ↦ y mean? - Mathematics Stack …
WEBApr 20, 2016 — f: x ↦ y means that f is a function which takes in a value x and gives out y. f: N → N means that f is a function which takes a natural number as domain and results in a natural number as the result. Because you're wrong: the → and ↦ arrows mean different things. Also, W is not the set of positive numbers: that's R +.
symbols - Arrow in text mode - TeX - LaTeX Stack Exchange
WEB3. Try A \verb|->| B. To me this is the simplest and most flexible solution, and renders nicely too (sure, it does not look like the right arrow in math mode but for many purposes it might be enough). You can control spacing very easily inside the verbatim. For instance, more spacing would be A \verb| -> | B. Both are shown below.
What does $\\rightarrow$ mean in $p \\rightarrow q$
WEBThe → → symbol is a connective. It's a symbol which connects two propositions in the context of propositional logic (and its extensions, first-order logic, and so on). The truth table of → → is defined to be that p → q p → q is false if and only if p p is true and q q is false. Indeed this is the same meaning of , but the difference ...

WEBAug 16, 2015 — You could use \overrightarrow: \overrightarrow{\dim} , \quad \overrightarrow{\text{dimension}} This and further alternatives can be found at the LaTeX-Community forum in the topic Extended Vector Arrow. So there are nice arrows with esvect: \vv{\dim} , \quad \vv{\text{dimension}} What is the difference between esvect and not …
\\Rightarrow vs. \\implies, and "does not imply" symbol
WEB265. To answer your first question, you should use \implies, not \Rightarrow. \Rightarrow is far too small to give a readable result and is not spaced properly. Knuth specially defined \iff to be used for equivalence and \implies is the same but for implication (from the amsmath package). An implication is not a relation like > and, therefore ...

WEBSep 28, 2015 — As in other answers it implements @BarbaraBeeton's suggestion of using the arrow head in the lasy fonts. The length parameter or \myscriptarrow is automatically scaled, so it should be same as for \myarrow. Equivalent result is obtained via shorter code which employs \vcenter: \vcenter{\hbox{\rule[-.2pt]{#1}{.4pt}}}%.
How to make \Rightarrow bold - TeX - LaTeX Stack Exchange
WEBFeb 2, 2019 — 3. In the modern toolchain, with unicode-math and running either LuaLaTeX or XeLaTeX, you can choose whatever font for bold math you want: p \boldsymbol{\Rightarrow} q \Rightarrow r. If you want all instances of \Rightarrow to be bold, you could select that one glyph from a font with a heavier weight: In the legacy toolchain, …
