Grammar

• Not to or to not ?

The default construction is not to + INF (like in I decided not to go). However the split infinitive construction to not + INF seems to be allowed as well (like in I decided to not go). Note that I decided not to go is not the same as I did not decide to go!

• half or half of?

[2], [3]

Both are usually valid (She spends half (of) her time travelling., Half (of) my friends live abroad.)

When using plurals, better specify the scope correctly (Half (of) my friends live abroad better than Half (of) friends live abroad)

half of before pronouns (Half of them)

half a usually ((half an apple is not a lot)), but a half also valid in measurements (a half pound)

• punctuations

comma — In an enumeration, a comma , before and is optional. Choose your favorite option and stick to it [4]. Adding this comma may clarify the enumeration if items are complex. This comma is called the serial comma or Oxford comma [5].

Writing tips

• Avoid passive voice
• Avoid unnecessary details
• Set the scene progressively (step by step)
• Use the colon correctly

We obtain the following theorem:           // -- BAD --
We obtain the following theorem.           // -- CORRECT --
Theorem 8. foo ...

From John Owens [7],[8]:

• Use et al. correctly. "et al." means et alia. Use it when there are 3 authors or more

AuthorOne
AuthorOne and AuthorTwo
AuthorOne et al.

• Don't use citation as words :

A similar strategy is described in [15].                        // --BAD-- citation as word, 
A similar strategy is discussed by 15.                    // ... imagine if citation uses superscript -> looks really silly
A similar strategy is discussed by AuthorOne et al. [15]        // --CORRECT--

• Use short citation to avoid repeat:

AuthorOne discusses this point further in her dissertation [AuthorOne 2002].  // --BAD-- name repeated
AuthorOne discusses this point further in her dissertation [2002].            // --BETTER--

• First person, passive voice: Please write in first person and avoid the passive voice.
• Hyphenation: “We built a high-performance implementation.” “high-performance” is hyphenated because “high” modifies “performance” not “implementation”. It's not a “high implementation”. Here, “high-performance” is an adjective. But: “Our implementation has high performance.” Here, “performance” is a noun. No hyphen. Similarly: “throughput-oriented workloads” or “GPU-based implementation”.
  For some words, it's not clear if it should be hyphenated or not (e.g. “e-mail” vs. “email”). The general trend in English is to move toward non-hyphenation (e.g. “to-morrow” became “tomorrow”) so if I'm unsure, I usually trend toward non-hyphenation.
• Serial comma: “The serial comma is the comma used immediately before a coordinating conjunction (usually and or or, sometimes nor) preceding the final item in a list of three or more items.” (Wikipedia). Short rule: always use it in because it avoids confusion.
• Use of the word “only”: Be precise with this word! For example, “I only eat apples” (doing nothing but eating apple) and “I eat only apples” (because I'm a horse or something).
• Writing units: If you're writing, say, “ten meters”, these are WRONG: “10m” or “10m”. It's “10 m” (non-breaking space, not italicized, 10~m in LaTeX). See package [siunitx]. Also, since "bit" is already an abbreviation of "binary digit", don't write "10 kb" but "10 kbit". "10 kB" is ok.

TO DO Have also a look at Writing Mathematical Papers in English (see References).

From http://ell.stackexchange.com/questions/820/is-it-less-than-or-lesser-than:

Less, lesser, and littler are all comparative forms of little. They are used like this:

• little - littler - littlest when you mean "small in size" (note: littler - littlest are in fact childish speech)
• little - less - least when you mean "small in amount"
• little - lesser - least when you mean "inferior or smaller in importance"

So if you mean one quantity or number is smaller than another, you say "less than".

You would say *less than* or *the lesser of*(?). Not lesser than.

However, it largely depends on the sentence in which you're using your particular example, as it may be that using 'fewer than' instead of 'less than' is correct. 'Less' means not as much 'Fewer' means 'not as many'

For example, if I'm holding three apples I have 'fewer than 4 apples'.

If I'm holding half a kilogram of sugar, I have 'less than a kilogram of sugar'.

From http://news.bbc.co.uk/2/hi/uk_news/magazine/7591905.stm:

more than / less than

greater than / less than

less / lesser / least - more familiar

few / fewer / fewest - less familiar

"- fewer is for numbers of separate items or people,

- less is for quantities not thought of in numbers: there were fewer people in the shops because there was less money

6 weeks or less

10 items or less - not correct, it should be 10 items or fewer.

However, "less than six weeks" is correct because we refer to a single period of time lasting six weeks, not to six individual weeks".

Indeed, 5 weeks and 2 days is less than six weeks.

But one can say "there are fewer weeks in two months than there are in one month".

Little vs small - see http://english.stackexchange.com/questions/31216/difference-between-little-and-small:

• When denoting size, there is little difference between "little" and "small".
• When denoting quantity, only little can be used.
  Also there is a difference between a little (as in I have a little experience teaching english, which means I have some experience but not much) and little (there is little difference means there is no difference, I have little experience teaching english)
