周五公众报告

报告题目： Remarkable and other fake cardinals.

报告人： Professor Ralf Schindler, University of Münster

时间地点： 5月18日下午4：00-5:00 后主楼1124

报告摘要：A remarkable cardinal, the prototype example of a "fake" large cardinal, is equiconsistent with each entry from a whole list of different set theoretical statements. We recently isolated a new forcing axiom, PFA^-, which is strictly between BPFA and PFA and which can be added to that list. Since then, other types of "fake" large cardinals have been isolated. In an attempt to compute the strength of "every uncountable universally Baire set has a perfect subset" we isolated a large cardinal concept which resembles remarkable cardinals. This is partly joint work with J. Bagaria, V. Gitman, and T. Wilson.

周五学院公众报告主旨：讲解现代数学中的基本概念、重要结果及其数学思想的起源、方法的创新等，扩展我们的教师和研究生的视野、提高数学修养以及增强学院的学术氛围。邀请各方向的专家用通俗易懂的报告内容、自由互动的讲解方式展现现代数学中重要的基本概念和深刻原理，让听众可以领略到现代数学理论其实是来源于一些大学或研究生阶段就熟知的古典数学中的想法和结论。希望这些报告有助于高年级的本科生、研究生和教师更全面的认识现代数学、享受数学之美。欢迎大家踊跃参与！
