I've been asked to use a given format for a paper and I have to use the following format for sections:
being size of the paragraph text 10pt and that of the section 11pt. I also have to reduce, respect to that of LaTeX, the spacing between the paragraph and the section title and change the enumeration to roman numbers. I have tried to make it with titleformat command but I could not reach the desired style. I hope you can help me! Thank you!
