Definition talk:Delta-Algebra

Can someone find a reference for this? I couldn't find anything on Googling (apart from this page itself) and it seems like just an alternative definition of a $\sigma$-algebra. Caliburn (talk) 15:40, 28 April 2022 (UTC)


 * I ought to be able to, I posted it up in the first place. Probably Kolmogorov and Fomin, which I never really got on with (apparently the translation was substandard) and I never got round to filling in the references. I'll get back to it in due course. --prime mover (talk) 15:47, 28 April 2022 (UTC)
