P-class is a proper subclass of NP-class; and more
JongJin Kim, GwangJin Kim, JongPyo Lee +5
We may give rise to some questions related to the mathematical structures of -class and -class. We have seen that one is a proper subclass of the other. Here we disclose mor…
New Gelfond-Type Transcendental Numbers
R. M. Chaphalkar, S. G. Hwang, C. H. Lee +1
It is well known that value at a non-zero algebraic number of each of the functions …
On generalized Witt algebras in one variable
Jonathan Pakianathan, Ki Bong Nam
We study a class of infinite dimensional Lie algebras called generalized Witt algebras (in one variable). These include the classical Witt algebra and the centerless Virasoro algeb…
The generalized Witt algebras using additive maps
Ki-Bong Nam, Moon Ok Wang
Wawamoto generalized the Witt algebra using Laurent extension of polynomial ring. We construct the generalized Witt algebra by using an additive map from a set of…
Generalized W-type and H-type algebras
Ki-Bong Nam
It is well known that the Poisson Lie algebra is isomorphic to the Hamiltonian Lie algebra. We show that the Poisson Lie algebra can be embedded properly in the special type Lie al…
Simple Lie algebras which generalize Witt algebras
Ki-Bong Nam
We introduce a new class of simple Lie algebras that generalize the Witt algebra by using "exponential" functions, and also a subalgebra thereof; and we show ea…
