The concept of things coming together, meeting, or becoming similar. This guide covers physical convergence, abstract convergence of ideas or trends, and mathematical/technical convergence.
Describing roads, rivers, people, or objects physically meeting at a point.
Used for rivers, roads, or groups of people physically merging or joining. Often implies a flowing together.
この川はあの川と合流する。

Similar to 収束 but often used in economics, biology, or formal contexts for convergence of traits or trends. Slightly more technical.
Means agreement or coincidence; can be used when opinions or results converge to the same point.
Used in mathematics, physics, or technology for sequences, series, or technologies merging.
Standard term for convergence of sequences, series, or iterative processes in mathematics.
この数列は0に収束する。

Also used in mathematics, sometimes for uniform convergence or in specific contexts like functional analysis.
Both mean convergence, but 収束 is more common and general. 収斂 is often used in formal, academic, or biological/economic contexts. In mathematics, 収束 is the default for sequence convergence, while 収斂 may appear in advanced topics.
English 'convergence' covers many meanings. Do not assume one Japanese word fits all. For physical meeting, use 合流; for abstract coming together, 収束; for agreement, 一致.
