<p>
Let X be a variety over F_p . Fix a prime l different from p, an algebraic closure \overline{Q_l} of Q_l, and a p-adic valuation v of the subfield of algebraic numbers in \oversline{Q_l} normalized so that v(p)=1. Let M be a \overline{Q_l}-sheaf on X such that for every closed point x in X the eigenvalues of the geometric Frobenius acting on M_x are algebraic numbers. Applying the valuation v to these numbers and dividing<br />by the degree of x over F_p, we get a collection of rational numbers, which are called slopes of M at x.<br /><br />In a joint work with K.Kedlaya we proved that if X is a smooth curve and M is an irreducible local system then for almost all x the gaps between two consecutive slopes of M at x are not greater than 1. (If M has rank 2 then one can even replace “almost all” by “all”, but in the rank 3 case this is false.) This result is equivalent to certain estimates for the p-adic valuations of almost all Hecke eigenvalues of cuspidal automorphic representations (in the case of function fields).<br /><br />I will say only a few words about the proof (which is based on the theory of F-isocrystals).

<h2>
Description
</h2>
<ul><li>
The Einstein Institute of Mathematics will host a 10 day undergraduate workshop, bringing together outstanding (2nd and 3rd year) undergraduate students from Israel and abroad.<br />The workshop will be centered around two seminar-style courses, each one consisting of talks given by the students themselves and moderated by a faculty member from the institute.<br />This year the topics are:
<ul><li>
<u>Topics in the Theory of Zeta and L-Functions </u> (moderated by <b>Jasmin Matz</b>).
</li>
<li>
Description: The Riemann zeta function is the prototypical example of a large zoo of ζ- and L-function. Such functions are of central interests in modern number theory. In this seminar we are going to study several examples with an emphasis on analytical and spectral aspects.
<ul><li>
<u>Polytopes </u> (moderated by <b>Eran Nevo</b>).
</li>
<li>
Description: Polytopes have fascinated humans since antiquity and are related to many areas of modern mathematics. We will study polytopes, focusing on connections between their geometric and combinatorial properties.
</li>
</ul><br />In addition, there will be minicourses by <b>Klaus Altmann</b> (FU Berlin) and <b>Jake Solomon</b> (HUJI), guest lectures, and a social program.<br />More information regarding the program will be posted <a href="http://www.math.huji.ac.il/~workshop" title="">here</a>, as it becomes available.<br />Check out the workshop's posters in <a href="/mathen/files/undergrad_workshop_2018_poster_english.pdf" title="">English</a> and <a href="/mathen/files/undergrad_workshop_2018_poster_hebrew.pdf" title="">Hebrew</a>!

</ul><h2>
Location and Dates
</h2>
<ul><li>
The workshop will take place at <a href="http://www.mathematics.huji.ac.il"> the Einstein Institute of Mathematics </a>, <a href="http://www.huji.ac.il"> the Hebrew University of Jerusalem </a>, Jerusalem, Israel.<br />Participants are expected to arrive the day before, on Sunday, October 1st, and the workshop will end on Thursday, October 11th in the afternoon.

</ul><h2>
Applications
</h2>
<ul><li>
To apply please send an email to <a href="mailto:huji.math.undergrad.workshop@gmail.com">huji.math.undergrad.workshop@gmail.com </a> with the following information:
<ul><li>
Your name, gender, address, and institution.
</li>
<li>
A grade transcript with a clear listing of the courses you've taken so far in your mathematical studies (an informal transcript is OK).
</li>
<li>
The name of a contact person from whom we may request a recommendation letter if needed.
</li>
</ul><br />An application with only partial information (for example, if you don't have a contact person who'll write you a letter), is better than no application at all!<br />Applications received by Friday, June 15th, 2018, will receive full consideration.
