My name is Lyosha Beshenov.

I decided to create a stand-alone blog in English for discrete personal and mathematical notes.

The blog is called “Radical Ideals”, and it’s an obvious algebraic pun:

• on the one hand, a radical ideal is an ideal I in a commutative ring that coincides with its radical Rad(I);
• on the other hand, a “radical ideal” is an extreme standard of perfection :D
