I am looking for informations about fig tree that are able to set figs
same year after freezing and recovering in same spring/summer.

What are the cultivars that could do this?

I would call these guys and see if they have a distributor near you.

Yes this guy is well known among german growers, but Bayernfeige (bavarian fig) is supposed to be a brown turkey type and this one isnt really cold hardy compared to other figs (guess -20 degree is just a marketing trick). And bavarian fig definetely cant bear any crop when freezing back. 

I would look after local romanian varieties, maybe you get some russian or bulgarian figs (would try michurinska-10 oder rdb).

@Sas: I have Bayernfeige Violetta, it is very slow growing for me and not very hardy as a small tree. Also, this fig has other synonims names, like Violetta and maybe Early Violetta. I have cultivar Peretta, which is more cold hardy, but it didn't fruit yet.

@PhilSH: I have already more fig tree cultivars collected from Romania, Bulgaria, Hungary but most of them are in stage of rooted cuttings. Michurinsk-10 and Ali-Pasha have fruited even in first year in pots. Also, Rdb has fruited first year in ground, very productive but not best tasting.

I am looking for real informations from other growers experiences about fig trees that could fruit same year after a totaly or partialy die-back!
