It conventional to use lower case bold for vectors and upper case bold of tensors.

Format can often be tricky because different physicist/mathematicians/authors have different preferences. In discrete math, a bold variable Z or R can correspond to the set of all integers or the set of all reals.
One of my physics professors used a bold variable to denote a vector. One other teacher I've had used bold variables in formulas to denote a constant rather than a value that was to be 'plugged in.'
Wikipedia confirms the use of bold variables as vectors, but again, there could be stylistic differences.
