The array approach is good to one lcd decomñposition but I see difficult to use in multiple lcd decompositions. I'm not sure what you're trying to achieve exactly---or should I say, what exactly your problem is?, but you can put more than one array environment into one math env. If that's not enoug...

I'm no LyX user, but this $\stackrel[n=1]{\infty}{\bigcup}X_{n}\in R.$ looks wrong to me: \stackrel expects exactly two parameters, and doesn't have an optional one. Thus, you're telling \stackrel to put an opening bracket over n---the rest of that statement above is not seen by \stackrel . Perhaps ...

In this case the top equation on page 2 is numbered 1.3 while the second equation on page 2 is numbered 2.1. Sorry if I misled you, I didn't keep in mind that the page cont...

How do you vertically center the text lines ? You can replace the inner alignment for the \parbox ---the second [b]---with [c]. In that case, you may want to replace the origin for the two \rotatebox commands to `cB', too. And what is the \strut command ? \strut is basically a box of zero width wit...

I just found that adding the following code to the previous MWE adds a vertical text line in the gray band, actually, there's nothing in that code providing a \rotatebox command. graphicx and rotating packages come to mind. but it's not properly centered inside. I don't see any \centering or simila...

I realize that I probably have to store the value of the words counter at the end of the environment in the aux file and then pull that number out on the next compilation in order to get this to work right (I've used this approach before in other single use cases), but am not sure how to do that he...
