Is there such a thing as fraud in mathematics? Can you commit fraud in a mathematics publication? Or is this a privilege of empirical sciences?

If a mathematician jumps from one bit of information to another that does not follow logically, from more basic principles, then, that's not fraud, but a logical fallacy, akin to saying 1+1=3. 

If an empirical scientist gets a results of 3.3341, but claims it was 3.7341 that's fraud.
Wikipedia defines fraud as "deliberate deception". A couple of mathematical frauds I could think of:


Passing off someone else's result as one's own; plagiarism.
Using a result in a proof although one knows full well that its preconditions are not met.
Making other claims one knows are false, e.g., "it is easy to see that" or "by a tedious computation we see that".


Fraud is certainly possible in mathematics. It's probably harder to distinguish fraud from bona fide errors in math than in other sciences. Who is going to prove that you knew your "simple but tedious enumeration" would not work? Conversely, reusing graphics ostensibly stemming from very different experiments is very hard to explain as a simple error.
