In summary, the cosmological constant does not need to change when approaching calculations in relativity with more dimensions. GR works with four-dimensional spacetime, but it is possible to work with fewer dimensions. The cosmological constant is not dependent on the number of dimensions, and its nature may change in different interpretations. This could be a question for the string forum.

This is an interesting question, and seems to relate strongly to GR, so I am moving the thread to the S&GR section, where I think you will quickly get a good answer.

The cosmological constant does not depend on the number of dimensions in which you are calculating.

GR is a theory of gravity developed by Albert Einstein in 1915, which describes the relationship between matter and spacetime and how they interact to produce the force of gravity.

The Cosmological Constant is a term included in Einstein's equations of GR to represent the energy density of the vacuum of space. It is denoted by the Greek letter lambda (Λ) and is responsible for the expansion of the universe.

In GR, gravity is described as the curvature of spacetime caused by the presence of mass and energy. Objects with mass cause spacetime to curve, and the curvature determines how objects move in the presence of gravity.

The Cosmological Constant is an important concept in cosmology as it helps explain the accelerated expansion of the universe. It is also used in models of the universe, such as the Lambda-CDM model, which describes the evolution of the universe with Λ as one of its key parameters.

Dark energy is a theoretical form of energy that is thought to be responsible for the expansion of the universe. The Cosmological Constant is one of the leading explanations for dark energy, as it has a similar effect on the expansion of the universe. However, there are still ongoing debates and research about the exact nature of dark energy and its relationship to the Cosmological Constant.
