          A simpler code with the diffcoeff package. The order of differentiation is automatically computed — I suppose k+l is k_1+k_2+l:



          documentclassarticle
          usepackagemathtools, diffcoeff
          DeclarePairedDelimiterabslvertrvert

          begindocument

          [
          abs*diffp[k_1,k_2,l]u_0
          x_1, x_2, t leq C
          ]

          enddocument


          enter image description here

          • I didn't know about diffcoeff. Nice. Off topic: k_1+k_2+l just to be compatible with order of powers in denominator? :-)

            Feb 22 at 14:09











          • @Sigur: it is a comparatively recent package. For the question: yes it is so. Of course, I understand that probably, $k$ denotes $k_1+k_2$, but there doesn't seem to be tools to use k in the numerator and k_1, k_2 in the denominator.

            – Bernard
            Feb 22 at 14:15











          • Is there any way to eliminate the parentheses around the variables in the denominator? IMHO, adding parentheses like this creates ambiguity and is wrong. See i.stack.imgur.com/Jc3v8.png The powers k_1, k_2 and l should be applied to the whole partial <variable> thing.

          • It seems to be hard-coded in the package for so-called long variables (it goes into the category, I suspect, because of the indices). As it's written in latex 3, which I don't master, I have no idea how to patch it, unfortunately. Maybe, ask a new question about this feature?

          You could write



          [leftlvertfracpartial^k+lu_0
          partial x_1^k_1partial x_2^k_2partial t^lrightrvert
          leq C]

            • The notation here is wrong I’m afraid. The k_1, k_2 and l should follow the variables, not the partial signs. See i.stack.imgur.com/Jc3v8.png

              Feb 22 at 13:55











            • @Sigur, it is not part of latex code, but drawn by Snipping Tool, which i use for copping image from pdf previewer to site. in it i select option Show Ink selection ...

            • Ah, OK. I use Shutter. Maybe there is such frame option there.

              – Sigur
              Feb 22 at 14:02











            • Thanks to you I've just created a plugin for Shutter to add 1px solid blue frame around the image. Now I need to know how to run it automatically when screen shot is created.

              – Sigur
              Feb 22 at 15:03











            • For the frame around formula in LaTeX, simply use boxed... inside the math context. Of course, to get the wide white horizontal margin you would have to manually add some space with hspace or qquad

                      • For the frame around formula in LaTeX, simply use boxed... inside the math context. Of course, to get the wide white horizontal margin you would have to manually add some space with hspace or qquad

                      Ah, OK. I use Shutter. Maybe there is such frame option there.

                      Thanks to you I've just created a plugin for Shutter to add 1px solid blue frame around the image. Now I need to know how to run it automatically when screen shot is created.

                      For the frame around formula in LaTeX, simply use boxed... inside the math context. Of course, to get the wide white horizontal margin you would have to manually add some space with hspace or qquad
