An introduction to the major and networking time for MUEUNJAE SCHOOL OF UNDERGRADUATE STUDIES
STUDENTS.

On Friday, September 26, the 2025 Department of Mathematics Open Math Lounge event was held in Room 401 of the POSTECH Mathematical Sciences Building (Math Lounge).

 The event was organized by the POSTECH Mathematics Undergraduate Student Council and was successfully conducted with the participation of 17 students, including 13 students from the MUEUNJAE SCHOOL OF UNDERGRADUATE STUDIES STUDENTS.

 Designed to introduce the mathematics major and promote interaction between mathematics undergraduates and MUEUNJAE SCHOOL OF UNDERGRADUATE STUDIES STUDENTS, the event began with an introduction to the student council. Participants were then invited to explore the Math Lounge, a dedicated common space for mathematics students.

 Following this, undergraduate students from the Department of Mathematics gave presentations sharing their experiences with the major and their research activities.

• Hyeonseong, Kim presented on the algebraic definition of cotangent spaces, offering insights into how abstract mathematical concepts are structured.
  
  



• Yunje Jeong shared his interdisciplinary research experience in the Department of Industrial & Management Engineering, highlighting real-world applications of mathematical methods.

  
  


• 
  
  Taeyung, Lee gave an overview of topics covered in general topology, illustrating the theoretical depth of the subject.
  
  



• Tae Jun Park discussed the matching problem in discrete mathematics, walking the audience through an engaging problem-solving process.

  
  

 After the presentations, participants enjoyed pizza together and engaged in open Q&A and casual discussion.

 The session provided a valuable opportunity for MUEUNJAE SCHOOL OF UNDERGRADUATE STUDIES STUDENTS to gain practical insights into mathematics courses, student life, and career paths, helping them make more informed decisions about their future majors.

 The POSTECH Department of Mathematics plans to continue its outreach efforts and provide diverse opportunities for undergraduate engagement, aiming to foster greater understanding and interest in the field of mathematics.
