New limits on neutrino non-standard mixings based on prescribed singular values
Wojciech Flieger, Janusz Gluza, Kamil Porwit
Singular values are used to construct physically admissible 3-dimensional mixing matrices characterized as contractions. Depending on the number of singular values strictly less th…

Matrix norms and search for sterile neutrinos
Wojciech Flieger, Franciszek Pindel, Kamil Porwit
Matrix norms can be used to measure the "distance" between two matrices which translates naturally to the problem of calculating the unitary deviation of the neutrino mixing matric…
