About Me
I am a PhD student in the Institute of Mathematics in the Hebrew University, studying set theory, under the supervision of Prof. Yair Hayut. I am mainly interested in large cardinal forcings and in particular combinatorial results that occur by changing cofinalities of successors of singular cardinals.
I received my MSc from Ben-Gurion University under the supervision of Prof. Menachem Kojman.
