Abstract Compactifying the E 8 non-critical string in 6D down to 5D, the 6D strings give rise to particles and strings in 5D. Using the dual M-theory description compactified on an elliptically fibered Calabi-Yau we compare some of the 5D BPS states to what one expects from non-critical strings with an E 8 chiral current algebra. The E 8 multiplets of particle states comprise of 2-branes wrapping on irreducible curves together with bound states of several 2-branes. 
Toroidal compactification of heterotic 6D non-critical strings down to four dimensions
Abstract The low-energy limit of the 6D non-critical string theory with N = 1 SUSY and E 8 chiral current algebra compactified on T 2 is generically an N = 2 U (1) vector multiplet. We study the
Investigating the BPS spectrum of non-critical En strings
Abstract We use the effective action of the En non-critical strings to study its BPS spectrum for 0 ⩽ n ⩽ 8. We show how to introduce mass parameters, or Wilson lines, into the effective action, and
BPS States of Exceptional Non-Critical Strings
We study the BPS states of non-critical strings which arise for zero size instantons of exceptional groups. This is accomplished by using F-theory and M-theory duals and by employing mirror symmetry
Abstract We study the compactification of the (2, 0) and type-II little-string theories on S 1 , T 2 and T 3 with an R-symmetry twist that preserves half the supersymmetry. We argue that it produces
Abstract Making use of non-perturbative U-duality symmetries of type II strings we construct new `superstring' vacua in three dimensions with N =1 supersymmetry. This has an interpretation as
Non-critical strings, del Pezzo singularities and Seiberg-Witten curves
Abstract We study limits of four-dimensional type II Calabi-Yau compactifications with vanishing 4-cycle singularities, which are dual to T 2 compactifications of the six-dimensional non-critical
E-, M- and (p;q)-strings
We use mirror symmetry, the rened holomorphic anomaly equation and modularity properties of elliptic singularities to calculate the rened BPS invariants of stable pairs on non-compact Calabi-Yau
A picture of D-branes at strong coupling
We use a phase space description to (re)derive a first order form of the Born-Infeld action for D-branes. This derivation also makes it possible to consider the limit where the tension of the D-brane
E8 × E8 small instantons in matrix theory
Abstract A formulation of new six-dimensional theories with (1, 0) supersymmetry and E 8 global symmetry is proposed. The model is based on the large- n theory describing n D-strings interacting with
Affine 7-brane backgrounds and five-dimensional EN theories on S1
Abstract Elliptic curves for the 7-brane configurations realizing the affine Lie algebras E n (1⩽n⩽8) and E n (n=0,1) are systematically derived from the cubic equation for a rational elliptic


Small E8 instantons and tensionless non-critical strings
T-duality is used to extract information on an instanton of zero size in the E8 × E8 heterotic string. We discuss the possibility of the appearance of a tensionless anti-self-dual non-critical string
Bound states of strings and p-branes
Abstract The recent discovery of an explicit conformal field theory description of Type II p-branes makes it possible to investigate the existence of bound states of such objects. In particular, it
Exact results for N=2 compactifications of heterotic strings
Abstract We search for N = 2, d = 4 theories which can be realized both as heterotic string compactifications on K3 × T 2 and as type II string compactifications on Calabi-Yau threefolds. In such
D-Brane Realization of N=2 Super Yang-Mills Theory in Four Dimensions
We develop and study a D-brane realization of 4D N=2 super Yang-Mills theory. It is a type IIB string theory compactified on R^6\times K3 and containing parallel 7-branes. It can also be regarded as
Instantons on D-branes
We consider type IIA compactification on K3. We show that the instanton subsectors of the worldvolume of N 4-branes wrapped around K3 lead to a Hagedom density of BPS states in accord with
M-theory on a Calabi-Yau manifold
Abstract We compactify M -theory on a Calabi-Yau manifold to five dimensions by wrapping the membrane and fivebrane solitons of the eleven-dimensional supergravity limit around Calabi-Yau two-cycles
Non-perturbative properties of heterotic string vacua compactified on K3 × T2
Using the heterotic-type II duality of N = 2 string vacua in four space-time dimensions we study non-perturbative couplings of toroidally compactified six-dimensional heterotic vacua. In particular,
N = 2 heterotic superstring and its dual theory in five dimensions
Abstract We study quantum effects in five dimensions in heterotic superstring theory compactified on K 3 × S 1 and analyze the conjecture that its dual effective theory is eleven-dimensional
Comments on string dynamics in six dimensions
We discuss the singularities in the moduli space of string compactifications to six dimensions with N = 1 supersymmetry. Such singularities arise from either massless particles or non-critical
On tensionless strings in 3 + 1 dimensions
Abstract We argue for the existence of phase transitions in 3 +_1 dimensions associated with the appearance of tensionless strings. The massless spectrum of this theory does not contain a graviton:
