The first Painlevé equation $ $ P_I:y”=6y^2-x $ $ has the symmetries $ $ x \mapsto \omega x \y \mapsto \omega^3 y$ $ for any fifth root of unity $ \omega$ . At the same time, the near-infinity asymptotics of $ P_I$ involve the five rays $ $ \Gamma_k= \left\{x:\arg x= \frac{2 \pi i k}{5}Read more
I’ve sorted out an image relational database, and created its original database in phpmyadmin (I use XAMPP). here is a picture of the database relation and this is a database image I created myself in phpmyadmin. this for its sql file — phpMyAdmin SQL Dump — version 4.7.4 — https://www.phpmyadmin.net/ — — Host: 127.0.0.1 —Read more

In Fourier theory, the pair composed of a variable and its Fourier transform is called conjugate variables, and one crucial property between the two is the uncertainty relation. This relation tells us that e.g. if one variable/function has a bounded (or compact?) support, its Fourier transform cannot have a bounded support as well. Now inRead more
Hello Community, To prepare for my exam I have completed many exercises. Most of them were solvable without any problems. But the following task I could not solve until now. It is: You are given the relation scheme R (A,B,C,D) with the three functional dependencies: AB → C, C → D, D → A InRead more
I am building a database with Python. I first type psql, then \i tournament.sql and \c tournament followed by \dt (to check if the table exist). Everything seems correct but when I try to run my python file(by doing python tournament.py), the error shows up saying the table does not exist. Please help a dbRead more

Background: https://oeis.org/A075308 (Number of n-digit perfect powers) Symmetric polynomials, the consecutive terms (1,6,15) in OEIS A050447, and the root-system of $ E_8$ Questions: Question I: In the empirical biomolecular problem on which my team is working, we have a theoretically crucial subset whose cardinality of 40 arises naturally and crucially as the sum of theRead more
As the title suggests, my question is devoted to understand (and maybe get some good references) the relation between the Igusa tower for a modular curves and $ p$ , or maybe $ T$ -adic modular forms. I post this question since I am reading Andreatta, Iovita and Pilloni’s paper “Le Halo Spectral”, where, firstRead more
