### Completeness of Root Functions of Regular Differential Operators

Sufficient conditions are obtained for which this system is a Riesz basis. Similar results are obtained for the operator generated by the multipoint problem for an ordinary differential equation of even order with coefficients containing the involution operator.

This system of odes can be written in matrix form, and we explain how to convert these equations into a standard matrix algebra eigenvalue problem. We then discuss the important application of coupled harmonic oscillators and the calculation of normal modes. The normal modes are those motions for which the individual masses that make up the system oscillate with the same frequency.

Next, to prepare for a discussion of partial differential equations, we define the Fourier series of a function. Then we derive the well-known one-dimensional diffusion equation, which is a partial differential equation for the time-evolution of the concentration of a dye over one spatial dimension.

### Spectral properties of ordinary differential operators with involuton

We proceed to solve this equation for a dye diffusing length-wise within a finite pipe. It was a great journey to go through this course. Jeffery explains the concepts very well. I hope this course will help me greatly in my other courses. Thank you Prof. The lectures are really impressive and explain derivations throughly. I cannot enjoy more on a math course than this one.
