I am interested in learning about standard monomial theory and Seshadri's program. I find the topic interesting, but I could not yet find a resource which kind of "dumbs it down" enough (a kind of introduction to a layman etc.). Could an expert please point me to some not so difficult to read introductions to SMT, if they exist? Eventually, I would like to understand Littelmann's path models, but I don't mind if the introduction doesn't get there. It will hopefully give me enough information to be able to understand Littelmann's work later on. Many thanks! (By the way, I am currently happy with working over $\mathbb{R}$ and $\mathbb{C}$ for the time being.)


Update: I found Seshadri's book really helpful to understand how SMT developed. Then it was easier to understand how Littelmann's path model came about. I also found some slides by Leonard Hardiman to be really helpful ([http://math.univ-lyon1.fr/~hardiman/hardiman\_slides\_C.pdf](http://math.univ-lyon1.fr/%7Ehardiman/hardiman_slides_C.pdf)), particularly because they contain some figures, which enables one to see what the path operators do, when applied to a particular path.



References on standard monomial theory
Seshadri wrote a book, "Introduction to the Theory of Standard Monomials" (<https://doi.org/10.1007/978-981-10-1813-8>), which is very easy-going, especially in the beginning. But perhaps it does not cover exactly what you're interested in?
