Hadamard / matrix product adjoint
Sorry, but this does not make sense. What is the Hadamard product of the matrix S and the vector Fx? |

Hadamard / matrix product adjoint
Err... So x is a matrix? |

Hadamard / matrix product adjoint
I could not parse your definition of the operator A. If D and S are matrices, do you build the Hadamard product with the matrix of the Fourier transform? |

Convergence in energy of bounded (semi)subharmonic functions
Sorry for the late reply: I guess the best thing would be to write an answer yourself so that this is kept for the records. |

Fredholm integral with functions constrained to [0;1]
For some reason I confused $g$ and $f$. Of course $f$ should be the unknown… Corrected. |

The most simple thing that comes to mind is the projected gradient method, see my update. |

What is an extragradient method?
Well, this shows that the term "extragradient" is indeed used differently. |
