    ]]>    My First Post2026-04-27T02:11:00+00:002026-04-27T02:11:00+00:00https://igorcarvalhh.github.io/jekyll/update/2026/04/27/my-first-postI’ve just uploaded to the arXiv my paper “Local Bernstein theory, and lower bounds for Lebesgue constants“. This paper was initially motivated by a problem of Erdős} on Lagrange interpolation, but in the course of solving that problem, I ended up modifying some very classical arguments of Bernstein and his contemporaries (Boas, Duffin, Schaeffer, Riesz, etc.) to obtain “local” versions of these classical “Bernstein-type inequalities” that may be of independent interest.

    Bernstein proved many estimates concerning the derivatives of polynomials, trigonometric polynomials, and entire functions of exponential type, but perhaps his most famous inequality in this direction is:

    ]]>    Welcome to Jekyll!2026-04-27T01:52:15+00:002026-04-27T01:52:15+00:00https://igorcarvalhh.github.io/jekyll/update/2026/04/27/welcome-to-jekyllYou’ll find this post in your _posts directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run jekyll serve, which launches a web server and auto-regenerates your site when a file is updated.

    Jekyll requires blog post files to be named according to the following format:

    YEAR-MONTH-DAY-title.MARKUP

    Where YEAR is a four-digit number, MONTH and DAY are both two-digit numbers, and MARKUP is the file extension representing the format used in the file. After that, include the necessary front matter. Take a look at the source for this post to get an idea about how it works.

    Jekyll also offers powerful support for code snippets:

    def print_hi(name)
  puts "Hi, #{name}"
end
print_hi('Tom')
#=> prints 'Hi, Tom' to STDOUT.

    Check out the Jekyll docs for more info on how to get the most out of Jekyll. File all bugs/feature requests at Jekyll’s GitHub repo. If you have questions, you can ask them on Jekyll Talk.
