Therefore it does not make sense to say that a matrix has definiteness. In addition, when we say M∈Rn×nM∈Rn×n positive definite, what is the first thing we do? We plug MM into a function(al) xT(⋅)xxT(⋅)x and check whether the function is positive for all ...

In 1995, building on earlier work by Bourgain, Wolff famously obtained (1) with using what is now known as the “Wolff hairbrush argument”, based on considering the size of a “hairbrush” – the union of all the tubes that pass through a single tube (the hairbrush “stem”) in ...

is symmetric and positive definite (with forming an orthonormal basis). Also, for any , is real, hence equal to . Thus we have a norm Since the real numbers commute with all quaternions, we have the multiplicative property . In particular, the unit quaternions (also known as , , or )...
