What is convergence trading?

Convergence trading, could you please elaborate on what it entails? I'm interested in understanding the concept and how it's applied in the world of finance and cryptocurrency. Does it involve taking advantage of price differences across markets or assets? Is it a form of arbitrage? How does one go about identifying opportunities for convergence trading, and what are the risks involved? I'm eager to gain insights into this strategy and how it can potentially generate profits in the ever-evolving landscape of financial markets.
