Isolated partial Hadamard matrices, and related topics
Teodor Banica, Duygu Ozteke, Lorenzo Pittau
We study the isolated partial Hadamard matrices, under the assumption that the entries are roots of unity, or more generally, under the assumption that the combinatorics comes from…
Monoidal Rigidity for Free Wreath Products
Pierre Fima, Lorenzo Pittau
In this note we observe that any compact quantum group monoidally equivalent, in a nice way, to a free wreath product of a compact quantum group by the quantum automorphism gro…
The free wreath product of a compact quantum group by a quantum automorphism group
Pierre Fima, Lorenzo Pittau
Let be a compact quantum group and be the quantum automorphism group of a finite dimensional C*-algebra . In this paper, we study the fr…
The free wreath product of a discrete group by a quantum automorphism group
Lorenzo Pittau
Let be the quantum automorphism group of a finite dimensional C*-algebra and a discrete group. We want to compute the fusion rules of $\widehatΓ\wr_* \math…
Regularity questions for complex Hadamard matrices
Teodor Banica, Lorenzo Pittau
We study the partial Hadamard matrices which are regular, in the sense that the scalar products between pairs of distinct rows decompose as sums of…
