But in the past few years, a more complex analysis of the problem has arisen.
After 1900, he worked in real and complex analysis.
He wrote over 200 papers, mainly in the fields of real and complex analysis.
Some of these areas are complex analysis, trigonometry, and series.
He was among the first to introduce complex analysis.
The works within this section are perhaps the second best known part of his research, after his contributions to complex analysis.
This directed his scientific research to the field of Complex Analysis.
"The tendency is be very excited about recent history, but the work has been more of chronicle than complex causal analysis," he said.
This criterion for uniform convergence is often useful in real and complex analysis.
He also made important contributions to complex analysis.
