I am not sure how to correctly use the word bound in this context:
All partial sums of two given sequences are bounded by a positive constant.
All partial sums of two given sequences are bound by a positive constant.

3'Bounded' has a different meaning to 'bound'. The former has to do with boundary, indicating the limits of something. 'Bound' is the past tense of 'bind'. I am not sure if this helps, but you may need a dictionary of mathematical terms.– WS2Apr 8, 2014 at 8:03

The difficulty you are facing is that there are two separate verbs in play here.
The verb bind means
Tie or fasten (something) tightly
Its past tense and past participle is bound
The verb bound (present tense) means
Form the boundary of; enclose
or
Place within certain limits; restrict
Bound can also mean
to move with a leap or series of leaps
In each of these cases, the past and past participle form of bound is bounded.
In the example given by the OP, it seems that the meaning is to place within limits (rather than to tie to). The verb would then be bound and the past participle is bounded. In the construction given, bounded is correct and bound is not.
The expression "to be bounded" meaning being limited or having a border is registered in English dictionaries.
