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:
Desired output:
math-mode spacing symbols math-operators

Sigmais a normal greek letter so has no spacing just asabchas no extra spacing, if you mean summation operator then usesumwhich is a different character and also specified as a math operator so has different 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.– David Carlisle

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.
