A note on the iterative approach to twisting type N solutions
L. Palacios, J. F. Plebanski
We present the results of the computation of a twisting type N solution to vacuum Einstein equations following an iterative approach. Our results show that the higher order terms f…
Boosting some type--D metrics
L. Palacios
We are presenting a general solution to the classical Einstein--Maxwell--dilaton--axion equations starting from a metric of type--D. Namely, this stringy solution is the result of…
A BRST charge for non-critical $\W_{2,s}$ strings
L. Palacios
We present a general argument for the construction of BRST charges of the `non-critical' $\W_{2,4}$, $\W_{2,5}$, $\W_{2,6}$, and $\W_{2,8}$ strings. This evidences the existence of…
Generalized $\W_3$ Strings from Free Fields
JM Figueroa-O'Farrill, CM Hull, L Palacios +1
The conventional quantization of w_3 strings gives theories which are equivalent to special cases of bosonic strings. We explore whether a more general quantization can lead to new…
Singular Contractions of W-algebras
C. M. Hull, L. Palacios
Many -algebras (e.g. the algebras) are consistent for all values of the central charge except for a discrete set of exceptional values. We show that such algebras can be c…
