# Notation

Hi there,

As part of my paper I need to define the minimum non-zero element of some set.
In particular I have,
$\zeta(j):= \displaystyle \min_{\substack{ k\in1..\kappa\\ t\in 1..\kappa+1,~i \in \mathcal I^{t,j},\\ b_i^{t,j} \mod \theta_k \neq 0}} b_i^{t,j} \mod \theta_k.$
But this is not very nice.
Is there maybe a nicer and more concise way to do this?

you don't absolutely have to put everything in the 'minimum of' sign you could just state

ζ(j):=min b$^{t,j}_{i}$ modθ$_{k}$

where k$\in${1,...,κ}, t$\in${1,...,κ+1},
i$\in$I$^{t,j}$ and b$^{t,j}_{i}$ modθ$_{k}$$\neq$0.

oh that's a good idea ... haha, don't know why i didn't think of that!
