We calculate the three loop gauge β-function for an abelian N = 1 supersymmetric gauge theory, using DRED. We construct a coupling constant redefinition that relates the result to the corresponding term in the NSVZ β-function, and by generalising this redefinition to the non-abelian case we derive the DRED three loop gauge β-function for the non-abelian case.

We have recovered four new records of the paleomagnetic field variability within Oxygen Isotope Stage 5 from deep-sea sediment cores of the Blake/Bahama Outer Ridge, western North Atlantic Ocean. These cores contain reproducible evidence of the Blake Event and are located within 300 km of cores used by Smith and Foster (1969) to define the Blake Event. Our new paleomagnetic records have both re...

We present a new development in our approach to the covariant quantization of superstrings in 10 dimensions which is based on a gauged WZNW model. The WZNW action reduces to our earlier free-field quantum action after a field redefinition, and to the GreenSchwarz classical action after constraining the current in Berkovits’ BRST charge to vanish. Physical states form the cohomology of a BRST ch...

We are taking a deeper look at charge and the Coulomb force other electric properties. There is an embedded 10-7 in constant that we will claim “only” needed to cancel out 107 squared. suggest three alternatives redefine give considerable simplification. The not as separate as, new suggested framework, it can be replaced with simply speed of light without affecting predicted output values. also...

Soft robotics is becoming an emerging solution to many of the problems in robotics, such as weight, cost and human interaction. In order overcome problems, bio-inspired designs have introduced new actuators, links architectures. However, complexity required models for control has increased dramatically geometrical model approaches, widely used rigid dynamics, are not enough these hardware types...

The ambiguities of the Seiberg-Witten map for gauge field coupled with fermionic matter are discussed. We find that only part of the ambiguities can be absorbed by gauge transformation and/or field redefinition and thus are negligible. The existence of matter field makes some other part of the ambiguities difficult to be absorbed by gauge transformation or field redefinition. PACS numbers: 11.1...
