Of course they are, there have been negotiations in the past and doubtless will be again at some point.
Such negotiations have never led to anything positive, but who knows, maybe this time will be different?
The public signs from Vlad the Invader are that he wants to negotiate, but not that he is willing to give up on any demand for Ukrainian territory or "neutrality".
My guess is Ukrainians will not be interested in any deal Vlad might offer and Vlad will not accept giving up Ukrainian territories or on EU and NATO membership for Ukraine.
So negotiations will go nowhere and both sides will use the winter to rearm and adjust for another go at it next year.
Just guessing, you never know for sure until it happens.
