Distinguishing virtual braids in polynomial time
Oleg Chterental
For we describe an -time algorithm that determines if a length virtual braid word in the standard presentation of the virtual braid group …
Yoshikawa moves on marked graphs via Roseman's theorem
Oleg Chterental
Yoshikawa [Yo] conjectured that a certain set of moves on marked graph diagrams generates the isotopy relation for surface links in , and this was proved by Swenton…
Virtual braids and virtual curve diagrams
Oleg Chterental
There is a well known injective homomorphism from the classical braid group into the automorphism group of the fr…
On orthostochastic, unistochastic and qustochastic matrices
Oleg Chterental, Dragomir Z. Djokovic
We introduce qustochastic matrices as the bistochastic matrices arising from quaternionic unitary matrices by replacing each entry with the square of its norm. This is the quaterni…
Normal Forms and Tensor Ranks of Pure States of Four Qubits
Oleg Chterental, Dragomir Z. Djokovic
We examine the SLOCC classification of the (non-normalized) pure states of four qubits obtained by F. Verstraete et al. The rigorous proofs of their basic results are provided and…
