Use of bolded variables in conference paper

Question

I'm currently writing my first conference paper and am trying to determine a variable naming convention. I like the approach used by Di Carlo in Dynamic Locomotion in the MIT Cheetah 3 Through Convex Model-Predictive Control:

[skipped irrelevant convention] Vectors are bold, upright, and lowercase (a,ω), matrices are bold, upright, and uppercase (A,Ω),and scalars are lowercase and italicized (a,ω).

The conference recommends following the IEEE guidelines outlined here, which does not comment on the topic. I assume it is thus up to me as the author to decide. Is bolding variables frowned upon? Is there a alternative, preferred method? Thank you!

Answer 1

For textbooks and self-published material, it is very good practice to follow a convention such as that proposed by Di Carlo, which is widely accepted as the general convention in mathematics.

However, it sounds like are talking about a submission to a conference to be collated and published as conference proceedings. This would typically have a review and editing process like submissions to any peer-reviewed journal would. In this case, especially since they don't stipulate any conventions, it matters less because they will likely edit your notation where applicable so that all the submissions to the conference proceedings are consistent in notation and formatting.
