# What is the interpretation of convergence and divergence of series and sequences in physics [closed]

Convergence and divergence are well known mathematical terms in the side of studying convergence and divergence of sequence and series , My question is about interpretation of those terms in physics ?

Note: For example the harmonic series :$\sum_{n\geq1}\frac 1 n$ is divergent what does it mean this in physics ?

• Is there any reason that the meaning should be different? – Arthur Mar 1 '18 at 23:14

• The literal question about "meaning in physics" is probably not quite the intended question, but, rather, "what is a mathematical interpretation that makes sense of physics needs?" – paul garrett Mar 1 '18 at 23:29
