It is well known that there are no static non-Abelian monopole solutions in pure Yang-Mills theory on Minkowski space R. We show that such solutions exist in SU(N) gauge theory on the spaces R2×S2 and R×S1×S2 with Minkowski signature (−+++). In the temporal gauge they are solutions of pure Yang-Mills theory on T × S, where T is R or S. Namely, imposing SO(3)-invariance and some reality conditio...

This work is motivated by the general interest in moduli spaces of based SU(r)instantons on S and on the connected sum of complex projective planes, which can be interpreted as moduli spaces of framed holomorphic vector bundles on blown up ruled surfaces. To be precise, we consider moduli of based SU(r)-instantons over all self-dual four dimensional manifolds, where the twistor bration contains...

We present the one-loop coefficients for an alternative Symanzik improved lattice action with gauge groups SU(2) or SU(3). Recently a new improved lattice action, called the square Symanzik action, was introduced by adding a 2× 2 Wilson loop to the Lüscher-Weisz Symanzik action [1, 2]: S({ci}) ≡ ∑

Using a new family of service disciplines, we provide weaker su cient conditions for nite stationary delay moments in FIFO multiserver queues. This extends the work in Sigman and Scheller-Wolf[1997] to GI=GI=s queues with = E[S]=E[T ] < s 1, where S and T are generic service and interarrival times, respectively. Thus, only when > s 1 are the familiar Kie er and Wolfowitz conditions actually nec...

Effects of water deficits on leaf turgor maintenance processes were analyzed for pear trees (Pyrus communis L. cv. "Barlett") grown in 120-liter containers. Four irrigation treatments were applied: a well-watered control treatment, a spring water stress cycle (Sp), a summer water stress cycle (Su), and a spring plus summer water stress cycle (Sp + Su). For the Sp treatment, water application wa...
