Spring snowpack, relied on by ski resorts and water managers throughout the Western United States, may be more vulnerable to a warming climate in coming decades, according to a new University of Utah ...
Extensions of No-Go Theorems to Many Signal Systems.
Concavity properties prevent the existence of significant landscapes in energy surfaces obtained by energy minimizations under constraints.
A No-Go Theorem for the Consistent Quantization of the Massive Gravitino on Robertson-Walker Spacetimes and Arbitrary Spin 3/2 Fields on General Curved Spacetimes
No-Go Theorem the Consistent Quantization the Massive Gravitino Robertson-Walker Spacetimes General Curved Spacetimes
2011/7/29
Abstract: We first introduce a set of conditions which assure that a free spin $\frac32$ field with $m\ge 0$ can be consistently ('unitarily') quantized on all curved spacetimes, i.e. also on spacetim...
