Thanks Aditya, but it does not work what it should?

With: \defineenumeration[demo][text={Demostració.\space},number=no, location=serried,width=fit,headstyle=italic,indentnext=yes, between=\blank,textdistance=.5em,closesymbol={\mathematics{\Box}}, style=normal,indenting=yes]

and \starttext

\startdemo Si $\text{area}(u) = N$ i $\text{area}(v) = M$, aleshores \startformula \startmathalignment \NC u \NC = \prod_{i=1}^N x_i^{-1} r_i x_i, \NR[+] \NC v \NC = \prod_{j=1}^M y_j^{-1} s_j y_j, \NR[+] \stopmathalignment \stopformula% per a alguns $x_i, y_j \in F(A)$, $r_i, s_j \in R$, on aquestes igualtats són dins el grup lliure $F(A)$.

I have that "per a alguns" is indenting but "on" is not.

Why?

Xan.

PS: Please, CCme I have

%Indentation \setupheads[indentnext=yes] \setupindenting[yes,small,first] \setupformulae[indentnext=yes] in headers. if I put setupformulae[identnext=yes] and ident=yes for enumerations _always_ have indenting after formula even if the text is following. Xan.
