# a technical problem?

Hi unlord and others, I see the ”underbraces” are now not functioning in the PM articles (this does not concern the PDF files). E.g.

in the article ”proof of fundamental theorem of algebra due to Cauchy”

the inequality after the words ”can make the estimation”

and in the article ”indirect proof of identity theorem of power series”

the equation (2).

The underbraces have before worked well .
