Mathematics

# Specific Topics

• Differential Geometry and Differential Forms
• Partial Differential Equations
• Ordinary Differential Equations
• Tensors

# Textbooks

• Boas - Mathematical Methods in the Physical Sciences
  Friendly but light on some details like the treatment of PDEs which isn't as general as it could be
  
  
• Blennow - Mathematical Methods for Physicists and Engineers
  Upper division level intro to vectors, tensors, PDEs, groups, etc.
  
  
• Arfken - Mathematical Methods for Physicists
  Terse at times but looks like a great reference

# Lecture Videos

• Sholapurkar - Complex Analysis (Bhaskaracharya Pratishthana)
  Introductory complex analysis course accessible after Calculus-IV
  
  
• NPTEL - Advanced Engineering Mathematics (IITR)
  {???} Less theoretical Kreyszig-based
