Laguerre polinomlari

Laguerre polinomlari (Lagger) --- matematik fizikada foydalaniladigan polinomlardan biri hisoblanadi. Edmond Laguerre sharafiga nomlangan. Laguerre differensial tenglamalarining yechimi hisoblanadi. $${\displaystyle xy''+(1-x)y'+ny=0,\ y=y(x)}$$ Ushbu tenglama ikkinchi tartibli chiziqli differensial tenglama hisoblanadi. Tenglamaning yechimlari yagona emas. n ta yechimi mavjud.

Ba'zida quyidagi tenglamaning ko`rinishi quyidagi ko`rinishga keltiriladi: $${\displaystyle xy''+(\alpha +1-x)y'+ny=0~.}$$
