No spacing after Sigma?

There seems to be barely any spacing (if at all) after Sigma, making it hard to read. Is this normal? Is there any way around it?



 $ Sigma_{v in V} alpha $


Output:

    Add your own horizontal space. See What commands are there for horizontal spacing?

    Sigma is a normal greek letter so has no spacing just as abc has no extra spacing, if you mean summation operator then use sum which is a different character and also specified as a math operator so has different spacing.

You should use sum, not Sigma, to create a summation symbol. The sum symbol is slightly larger than Sigma when used in text style, and a whole lot larger when used in display style. In addition, the math type of sum is math-op ("math operator"), whereas the math type of Sigma is math-ord ("ordinary atom"); this strongly affects the amount of whitespace TeX inserts before and after the symbol.



enter image description here



documentclass{article}
begin{document}
$Sigma_{iin V} beta_i quad
sum_{iin V} beta_i quad
sumlimits_{iin V}beta_i quad
{displaystylesumnolimits_{iin V} beta_i} quad
displaystylesum_{iin V} beta_i$
end{document}
