Is -はない just another way of saying -じゃありません?


In the sentence: 彼の論文には大した価値はない

Is the -はない another way of saying -じゃありません or -ではない?  
And is it read as wanai or hanai?




I would advise you to read up on the differences between all conjugations of
the copula だ/である/です and the existence verbs いる and ある.

  1. "~はない" (read as "wa nai") means "~ is not present(Lit: not exist)".

The `ない` is the negated form of the existence verb `ある`.

  2. "~ではない" (de wa nai) means "it is not ~"

`ではない` is the negated form of the copula (`である`). It can also be colloquially
shorted to `じゃない`. The polite form is `ではありません`, and it's corresponding
shortened form is `じゃありません`.

So to answer your question more directly, ~はない is not the same as
じゃありません/ではない.
