Discussion Overview
The discussion revolves around finding practical resources and examples for performing integrals over surfaces and volumes in the context of general relativity and manifold theory. Participants express a desire for concrete examples to better understand the application of theoretical concepts.
Discussion Character
- Exploratory
- Technical explanation
- Homework-related
Main Points Raised
- One participant seeks resources that provide numerous examples of integrals over surfaces and volumes in general relativity, expressing a need for practical applications of theoretical knowledge.
- Another participant suggests "A Relativist's Toolkit: The Mathematics of Black-Hole Mechanics" by Eric Poisson, mentioning its potential usefulness despite not directly addressing the participant's request.
- There is a discussion about the challenges of understanding concepts like pulling back a metric onto a submanifold and working with normal vectors, indicating a desire for more concrete examples to clarify these subtleties.
- One participant references Poisson's book, noting that it covers hypersurfaces but does not mention pullbacks, and expresses uncertainty about the number of examples in other recommended texts on differentiable geometry.
- Another participant mentions a book by Orodruin that includes a chapter on calculus on manifolds, suggesting it may contain relevant information or additional resources.
- There is a light-hearted exchange about the ongoing study of Wald's work, indicating a shared experience among participants regarding the complexity of the material.
Areas of Agreement / Disagreement
Participants generally agree on the need for practical examples and resources, but there is no consensus on specific texts that meet these needs, and multiple suggestions are offered without clear preference.
Contextual Notes
Some participants express uncertainty about the number of examples available in the recommended books, and there is a mention of a long time since one participant last reviewed a particular resource, indicating potential limitations in their current knowledge of available materials.
