Question

All arguments are stated in simple brackets.
​

Answer 1

Furthermore, in theory, braces are used to denote the anticommutator, where {a,b} is defined as ab + ba. The Lie bracket of a Lie algebra is a binary operation ...

Answer 2

Answer:

In mathematics, brackets of various typographical forms, such as parentheses ( ), square brackets [ ], braces { } and angle brackets ⟨ ⟩, are frequently used in mathematical notation.[1] Generally, such bracketing denotes some form of grouping: in evaluating an expression containing a bracketed sub-expression, the operators in the sub-expression take precedence over those surrounding it. Additionally, there are several uses and meanings for the various brackets.[2]

Historically, other notations, such as the vinculum, were similarly used for grouping. In present-day use, these notations all have specific meanings. The earliest use of brackets to indicate aggregation (i.e. grouping) was suggested in 1608 by Christopher Clavius, and in 1629 by Albert Girard
