Moreover, some of them do not admit even…
2013-12-23 10:00-11:00 FAMNIT-SEMIN Bojan Kuzma When Hadamard and usual powers coincide? We classify real matrices where the standard power coincides with the Hadamrad entry-wise. The problem appeared recently in vol 51 of IMAGE journal. Time permitting we will present some further problems from…
