In this paper we analyze the flow of probability in this system by expressing the ideal Black-Scholes equation in the Hamiltonian form. We then analyze how the non-conservation of probability affects the stability of the prices of the Stocks. Finally, we find the conditions under which the probability might be conserved in the market, challenging in this way the non-Hermitian nature of the Black-Scholes Hamiltonian.}, language = {English}, urldate = {2021-02-03}, journal = {arXiv.org}, author = {Arraut, Ivan and Au, Alan and Tse, Alan Ching-biu and Marques, Joao Alexandre Lobo}, year = {2020}, note = {Place: Ithaca, United States Publisher: Cornell University Library, arXiv.org Section: Quantitative Finance University: Cornell University Library arXiv.org}, keywords = {General Finance}, pages = {1--10}, }
