Is the Kronecker delta a function?
The Kronecker delta function is a powerful tensor that helps to compact and simplify long, complex expressions. The Kronecker delta function and the Levi-Civita tensor are two of the most popular tensors in the technical domain.
What does the Kronecker delta represent?
In mathematics, the Kronecker delta is a symbol, written as δij, depending on two integral numbers i and j. The symbol designates the number 1 if i = j and 0 if i ≠ j: The symbol is named after the German mathematician Leopold Kronecker (1823-1891).
What is the property of Kronecker delta?
Kronecker delta δij - is a small greek letter delta, which yields either 1 or 0, depending on which values its two indices i and j take on. The maximal value of an index corresponds to the considered dimension, so in three-dimensional space i and j run from 1 to 3. Kronecker delta is equal to 1, if i and j are equal.
