SU(2/1) superchiral self-duality: a new quantum, algebraic and geometric paradigm to describe the electroweak interactions
Published 2021-04-01“…Abstract We propose an extension of the Yang-Mills paradigm from Lie algebras to internal chiral superalgebras. We replace the Lie algebra-valued connection one-form A, by a superalgebra-valued polyform A ˜ $$ \tilde{A} $$ mixing exterior-forms of all degrees and satisfying the chiral self-duality condition A ˜ = ∗ A ˜ χ $$ \tilde{A} =^{\ast }{\tilde{A}}_{\chi } $$ , where χ denotes the superalgebra grading operator. …”

Classical Lie bialgebras for AdS/CFT integrability by contraction and reduction
Published 2023-06-01“…The two major steps in this construction consist in the contraction to a 3D Poincaré superalgebra and a certain reduction to a deformation of the $\mathfrak{u}(2|2)$ superalgebra. …”

New R-matrices with non-additive spectral parameters and integrable models of strongly correlated fermions
Published 2020-03-01“…Abstract We present a general formula for constructing R-matrices with non-additive spectral parameters associated with a type-I quantum superalgebra. The spectral parameters originate from two one-parameter families of inequivalent finite-dimensional irreducible representations of the quantum superalgebra upon which the R-matrix acts. …”

Three-dimensional exotic Newtonian supergravity theory with cosmological constant
Published 2021-07-01“…The underlying new non-relativistic superalgebra is obtained by expanding the $${\mathcal {N}}=2$$ N = 2 AdS superalgebra and can be written as two copies of the enhanced Nappi–Witten algebra, one of which is augmented by supersymmetry. …”

Conformal higher-spin symmetries in twistor string theory
Published 2014-12-01“…It is shown that similarly to massless superparticle, classical global symmetry of the Berkovits twistor string action is infinite-dimensional. We identify its superalgebra, whose finite-dimensional subalgebra contains psl(4|4,R) superalgebra. …”

Carrollian and non-relativistic Jackiw–Teitelboim supergravity
Published 2023-02-01“…The extended Newton–Hooke structure, and, in particular, the invariant metric necessary for the BF construction of non-relativistic JT supergravity, is obtained by performing an expansion of the $$\mathcal {N}=2$$ N = 2 AdS $$_2$$ 2 superalgebra. Subsequently, we introduce the extended AdS $$_2$$ 2 Carroll superalgebra, and the associated invariant metric, as a suitable redefinition of the extended Newton–Hooke superalgebra. …”

The linear $\protect \mathfrak{n}(1|N)$–invariant differential operators and $\protect \mathfrak{n}(1|N)$–relative cohomology
Published 2020-03-01“…Over the $(1,N)$-dimensional supercircle $S^{1|N}$, we classify $\mathfrak{n}(1|N)$-invariant linear differential operators acting on the superspaces of weighted densities on $S^{1|N}$, where $\mathfrak{n}(1|N)$ is the Heisenberg Lie superalgebra. This result allows us to compute the first differential $\mathfrak{n}(1|N)$-relative cohomology of the Lie superalgebra $\mathcal{K}(N)$ of contact vector fields with coefficients in the superspace of weighted densities. …”

Tensor hierarchy algebras and extended geometry. Part II. Gauge structure and dynamics

This tensor hierarchy algebra is a non-contragredient superalgebra, generically infinite-dimensional, which is a double extension of the structure algebra of the extended geometry. …”
