Technical support (often shortened to tech support) refers to services that entities provide to users of technology products or services. In general, technical support provides help regarding specific problems with a product or service, rather than providing training, provision or customization of the product, or other support services. Most companies offer technical support for the services or products they sell, either included in the cost or for an additional fee. Technical support may be delivered by phone, e-mail, live support software, live chat or website, or other tools where users can log an incident. Larger organizations frequently have internal technical support available to their staff for computer-related problems. The Internet can also be a good source for freely available tech support, where experienced users help users find solutions to their problems. In addition, some fee-based service companies charge for premium technical support services.

Hi,
I have a question concerning the asymptotic boundary conditions on matter fields and the Riemann tensor. What is the precise relation between saying that "the matter fields go to zero at spatial infinity" and "the matter fields have compact support"? And how natural is it to state that...
f(x,y) = x + y is the joint probability density function for continuous random variables X and Y. The support of this function is {0 < x < 1, 0 < y < 1}, which means it takes positive values over this region and zero elsewhere.
g(x) = x + (1/2) is the probability density function of X...
