Generalized binomial transform applied to the divergent series
Hirofumi Yamada
The divergent series for a function defined through Lapalce integral and the ground state energy of the quartic anharmonic oscillator to large orders are studied to test the genera…
Delta expansion and Wilson fermion in the Gross-Neveu model: Compatibility with linear divergence and continuum limit from inverse-mass expansion
Hirofumi Yamada
We apply the -expansion to the Gross-Neveu model in the large limit with Wilson fermion and investigate dynamical mass generation from inverse-mass expansion. The dimensionl…
Estimates of critical quantities from an expansion in mass: Ising model on the simple cubic lattice
Hirofumi Yamada
In the Ising model on the simple cubic lattice, we describe the inverse temperature and other quantities relevant for the computation of critical quantities in terms of a dimen…
Delta expansion at low temperatures
Hirofumi Yamada
In the low temperature phase of the square Ising model, we describe the inverse temperature beta as the function of a squared mass M and study the critical behavior of beta(M) via…
Critical exponents from large mass expansion
Hirofumi Yamada
We perform estimation of critical exponents via large mass expansion under crucial help of delta-expansion. We address to the three dimensional Ising model at high temperature and…
Large-order aspects of the delta-expansion in low-dimensional Ising models
Hirofumi Yamada
We investigate the large order aspects of the delta-expansion under the estimation procession of the critical quantities. As illustrative examples, we revisit one-dimensional Ising…
