I am reading the paper in this link https://dl.dropboxusercontent.com/u/20327748/99-16.ps.pdf
Please help me in the notation used in page 5, $(M \vee \phi_n)\wedge M$
it is in line 2 of page 5.
Thank you

I think it would be best to send the authors an email and ask them, since they are the only ones who knows by certain. Nevertheless, let me make a guess:
I think that $$ u\wedge M=\min(u,M) $$ and that $$ u\vee M=\max (u,M). $$ I'm not certain of what they want to do, but I guess that they are cutting the sequence $\phi_n$ off at the values $\pm M$ (in that case, I'd put the minus sign at a different place).
