报告题目:The homomorphism-homogeneity of algebraic structures
报告摘要:A countable structure A is said to be homomorphism-homogeneous if every homomorphism between its finitely generated substructures extends to an endomorphism of A. In this talk, I will give a complete and explicit classification of homomorphism-homogeneous finite semilattices, addressing an open problem posed by Dolinka and Masulovic in 2011. This is joint work with W. Yang.
