Victor Ivrii is a notable mathematician known for his contributions to several areas of mathematics, particularly in analysis and partial differential equations. He has worked on topics such as microlocal analysis, pseudodifferential operators, and the theory of elliptic operators. Ivrii has also been involved in mathematical education and research, and he has authored a number of papers and texts in his field.

As of my last knowledge update in October 2021, Vinayak Vatsal does not refer to a widely recognized public figure, concept, or entity. It's possible that it could be a name of a person, perhaps a local figure, an emerging personality, or a reference in a specific context or region that has gained prominence after that date.

Walter Craig is a mathematician known for his work in the fields of applied mathematics and partial differential equations, particularly in relation to fluid dynamics and wave phenomena. He has made significant contributions to the understanding of nonlinear wave equations, including topics like dispersive and hyperbolic equations. Additionally, Craig has focused on the mathematical analysis of various physical systems, often employing techniques from functional analysis and asymptotic analysis.

William Metzler could refer to various individuals, but one notable figure with that name is William H. Metzler, an American psychologist known for his work in educational psychology and learning theory. In particular, he made contributions to the understanding of how language and cognition interact in the learning process.

Yael Karshon might refer to a person's name, but I don't have specific information on an individual by that name. It's possible that they could be a private individual, a professional in a certain field, or someone who has gained some recognition after my last update in October 2021.

As of my last knowledge update in October 2021, Yvonne Pothier may not refer to a widely recognized public figure, concept, or term that is documented in mainstream sources. It's possible she could be a private individual or a lesser-known figure. If Yvonne Pothier has gained prominence or relevance after that date, I would not have that information.
