thank you for assistance 
If you enable the template debugger and visit a category. You can search for the category name and find the variable that outputs the current category.
When you find it you can echo the category like: {$variable.category}

i have to test
[quote]
{foreach from=$categories item=âsubcategoryâ}
{$subcategory.category}
{/foreach}
[/quote]
and the display is root category (array 7)
thx for the responses
no answer?
I put the question differently :
What is the syntax smarty to cross the array $categories to arrive at the data in $subcategories when I display the same category?
thx ! 
Didnât you want to display the CURRENT category?
{$category_data.category}
ok but I want to display all the attached categories and not only the selected category.
one should be done a {foreach} or {section} on the preceding or current category.
It allows to have the previous nearby categories when we show the last category.
exemple not correct :
[quote]
{if $subcategories}
{foreach from=$subcategories item=category}
{$category.category}
{/foreach}{else}
{foreach from=$category_data item=category}
{$category_data.category}
{/foreach}
{/if}
[/quote]
thx !
Have you looked at the categories_pages/categories_dtree.tpl templates?
I think it does just that.

Yes but it display the subcategory when I am in the current categorie and I want to display the parent category of the subcategory.
exemple :
categorie A
=> subcategorie B
item = 1
item = 2
item = 3
=> subcategorie C
item = 1
item = 2
item = 3
i want to display on sidebox the links of the subcategorie B + items when i have the shown articles of the categorie C.
undestand my request ?
a simple recall of the preceding category.
thx !
