Linked from

The 12 pages that link to Hadamard product, each with the reason it gives.

• ConvolutionCompared with: It is a direct elementwise operation, unlike convolution's shifted accumulation.

• Matrix multiplicationCompared with: It multiplies corresponding entries rather than taking row–column dot products.

• Riemann zeta functionRelated: Hadamard’s factorization of the completed zeta function links its zeros to its global form.

• Dot productCompared with: It uses the same componentwise multiplication but leaves the products as separate entries.

• Identity matrixCompared with: Under entrywise multiplication, the identity matrix does not preserve arbitrary matrices.

• Matrix exponentialCompared with: Entrywise multiplication defines a different algebra from the one used in the matrix exponential.

• Euler productCompared with: It factors by zeros rather than by primes and arithmetic local data.

• Scalar multiplicationCompared with: It scales entries separately instead of applying one scalar to the whole vector.

• Complex multiplicationCompared with: It multiplies corresponding entries rather than composing transformations through matrix multiplication.

• Cauchy productCompared with: Unlike the Cauchy product, it multiplies matching coefficients instead of summing across diagonals.

• Riemann–von Mangoldt formulaRelated: The product representation of the completed zeta function helps connect zeros to its growth.

• De Bruijn–Newman constantRelated: The product representation connects the deformed function to the locations of its zeros.
