What's ordinary derivative of the kronecker delta function? I have used "ordinary" in order not to confuse the reader with the covariant derivative. I have tried the following: $$\delta [x-n]=\frac...

Oct 29, 2020 · Could it be you're confusion the kronecker delta with the dirac delta function? Integrating over the kronecker delta multiplied by any function is always 0 since the kronecker delta is zero …

Jun 19, 2016 · However there is an easy notation generalising the Kronecker δ δ that allows you to test all kinds of relations, including set membership, which is the Iverson bracket: the convention that by …

Sep 28, 2023 · Let δij δ j i be the Kronecker delta function, i.e. 1 1 if i = j i = j and 0 0 otherwise. Then, it is easy to verify that this value is a rank 2 mixed tensor of one covariant index and one contravariant …

Why not use the matrix to represent the Kronecker delta function? The answer is: for the same reason we use notation like f(x) f (x) and formulas when dealing with functions, instead of using their graphs.

Jan 10, 2016 · 2 You presented two formulas for Kronecker delta and Dirac delta, neither or which are really used as definitions of those concepts. In practical terms, a remedy for confusion is to read the …

This is known as the Kronecker Delta instead of the Dirac Delta function just for clarity.

Jan 5, 2022 · This is the discrete equivalent to the Poisson summation formula or the formula you wrote. So the Kronecker delta is discrete equivalent of the Dirac delta and (1) (1) is saying that the Discrete …

Aug 23, 2021 · Am I missing something from the above discussion? The above summation representation instead seems to represent a Kronecker comb (mentioned later in the same article). Is …
